Exercise 2. Have you ever wondered why children have different heights? Some children grow taller and some end up being shorter than average. To answer this question Scientists have Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date come closer and researched about the parameters in the form of variables that are the cause of height. Therefore, a Class 9 Maths Chapter 2 Question Answer Date variable can be any Class 9 Maths Chapter 12 Question Answer Code trait, condition or factor that can change by only differing amounts or it is the unknown Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date term whose value is not known.

Not only that, the height of kids is also dependent on their DNA that means Class 9 Maths Chapter 2 Question Answer Date if their parents are tall then there are more chances of them being tall whereas short parents usually have short Chapter Question 2 9 Class Date Maths Answer Class 9 Maths Chapter 2 Question Answer Date kids. The height of the kid is also dependent class 9 maths chapter 2 question answer date the rate of Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date work or activities.

It is believed that children with more activities like jumping, running, skipping etc tend to grow faster. Thus, Class 9 Maths Chapter 2 Question Answer Date nutrients, DNA and activities are the three variables that control the height in our body. These variables keep changing from body to body. For example, while cooking dal we know that the quantity of water is thrice the quantity of Class 9 Maths Chapter 2 Question Answer Date lentils.

That you can add 1 cup lentils to three cups of water. This process can be expressed as. Here, the quantity of lentil is variable. That means if the quantity of lentils changes then the quantity of water also Class 9 Maths Chapter 2 Question Answer Date changes. There is one interesting thing about constants and that is this it never changes. A constant is actually a value that class 9 maths chapter 2 question answer date a fixed number on its.

Thus, x is a variable. Can Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date Constant be a Coefficient Too? Since now we already know about variables, it is easier for us to understand the Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date constant and coefficient. Class 9 maths chapter 2 question answer date coefficient is usually the number that is multiplied with the variable or letters. Also, in the term y, it can be considered as the coefficient of y because y can Class 9 Maths Chapter 2 Question Answer Date be written as 1xy.

The coefficient is the number which is always multiplied with the variables but constants are terms Class 9 Maths Chapter 2 Question Answer Date without variables. Therefore, coefficients cannot be called as constants and vice versa. In the aforementioned example, -7 is constant. Sometimes Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date terms are also a part of the sequence which is separated by commas.

Like Terms. Like terms are the terms having the same variables raised to the same power. The word Polynomial is derived from the word poly "many" and class 9 maths chapter 2 question answer date "term". It is an expression consisting of many terms such that each term holds at least one variable. The variables can be raised to the power and further multiplied by a coefficient but Class 9 Maths Chapter 2 Question Answer Date the simplest polynomials hold one variable.

A polynomial can also not have infinite terms. It always has a finite sum of terms with all variables having whole number exponents and no variable as denominator. Polynomials are composed of the following:. Variables such as g, h, x, y.

Exponents such as 2 in y 2 or 5 in x5. It is simply Class 9 Maths Chapter 2 Question Answer Date the highest of the powers or exponents on the terms present in the algebraic expression. Example: In 7x � 5, the first term is 7x, whereas the second term is The power on the variable of the given first term Class 9 Maths Chapter 2 Question Answer Date is one and on the second term is zero. Since, the highest exponent is one, the degree of polynomial is also class 9 maths chapter 2 question answer date. Polynomials can be classified on the basis of:.

Number of terms. Degree Class 9 Maths Chapter 2 Question Answer DateClass 9 Maths Chapter 2 Question Answer Date trong> of polynomial. A polynomial either has one term, two terms, three terms or more than three terms. The Degree Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date of Polynomial is considered as the highest value of the exponent in the expression because it is the largest exponent.

We can also call it an order of the polynomial. While finding the degree of the polynomial, remember that the polynomial Class 9 Maths Chapter 2 Question Answer Date powers of the variables must be either in an ascending or descending order. Linear Polynomial: If the expression holds degree Class 9 Maths Chapter 2 Question Answer Date 1 then we can call it a linear polynomial.

Quadratic Polynomial: If the expression holds degree 2 then it can be called a quadratic polynomial. Cubic Polynomial: If the expression holds degree 3 then it will be called a cubic Class 9 Maths Chapter 2 Question Answer Date polynomial. If the value of every coefficient of a variable is zero then it is called the zeros of a Polynomial.Class 9 Maths Chapter 2 Question Answer Date

In order to find the relationship between the zeroes and coefficients of a given quadratic polynomial, we can find the zeros of the polynomial by factorisation method that is, by taking the sum and product of these zeros. There are Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date four main polynomial operations which are:. Addition of Polynomials. Subtraction of Polynomials. Multiplication of Polynomials. Division of Polynomials. Every operation Class 9 Maths Chapter 2 Question Answer Date Class 9 Maths Chapter 2 Question Answer Date on polynomial class 9 is explained below using solved examples.

Let's discuss the division of fractions. Students can divide a fraction by whole number and a whole number by fraction. Anything is possible here. Here is a particular case to keep in mind.

If two fractions for which numerator and denominator are in reverse order, then they are called as reciprocals to each other. Their product is always 1. In the same way, while dividing mixed fractions with a whole number, students need to change the mixed fraction into improper fractions. Then it is easy to divide and solve. Next, we have to learn to divide a fraction with another fraction by changing one of the fractions into its reciprocal form.
