The first section is the introduction with no exercise. The Second section discusses a particular cpass of algebraic expression called polynomials.
The Third section explains the zeros of polynomials whereas the Fourth section discusses the Remainder Theorem. Factorisation of Polynomials and identities are revisited in fifth and sixth section. 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 come closer and researched chpater the parameters in the form of variables that are the cause of height.
Therefore, a variable can be any trait, condition or factor that can change by only differing amounts or it is the unknown term whose value is not known. Not only that, the height of kids is also dependent on their DNA that means if their parents are tall then there are more chances of them being tall whereas short parents usually have short kids.
The height of the kid is also dependent on the rate of work or activities. It is believed that children with more activities like jumping, running, skipping etc tend to grow faster. Thus, 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 flass that the quantity of water is thrice the quantity of 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 changes.
There is one interesting thing about constants and that is this it never changes. A constant is actually a value that is a fixed number on its. Thus, x is a variable. Can Constant be a Coefficient Too? Since now we already know about variables, it is class 9 maths chapter 2 question answer free for us to understand the constant and coefficient.
A coefficient is classs the number that is multiplied with chapted variable or letters. Also, in the term y, it can be considered as the coefficient of y because y clasz be written as 1xy. The coefficient is the number which is always multiplied with the variables but constants are terms without variables. Therefore, coefficients cannot be called as constants and vice versa.
In the aforementioned example, -7 is constant. Sometimes terms are also a part of the sequence which is separated by commas. Like Terms. Like terms class 9 maths chapter 2 question answer free the terms having the same variables raised to the same power.
The word Polynomial is derived from the word poly "many" and nominal "term". It is class 9 maths chapter 2 question answer free 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 the simplest polynomials hold one variable. A polynomial can also not have infinite terms. It always has clwss 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 the highest of the powers or exponents on the terms present in the algebraic expression. Example: In 7x � 5, class 9 maths chapter 2 question answer free first term is 7x, whereas the second term is The power on the variable of the given first term is one and on the second term is zero.
Since, the highest exponent is one, the degree of polynomial is also 1. Polynomials can be classified on the basis of:. Number of terms. Degree of polynomial. A polynomial either has one term, two terms, three terms or more than three terms. The Class 5 Maths Chapter 6 Question Answer Re Degree 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 powers of the variables must be either in an ascending or descending order. Linear Polynomial: If the expression holds degree 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 polynomial. If the value of every coefficient of a variable is zero then it is called the zeros of a Polynomial. In order to find the relationship between the zeroes and coefficients of a given quadratic polynomial, we can find the zeros of class 9 maths chapter 2 question answer free polynomial by factorisation method that is, by taking the sum and product of these class 9 maths chapter 2 question answer free. There are four main polynomial operations which are:.
Addition of Polynomials. Subtraction of Polynomials. Multiplication of Polynomials. Division of Polynomials. Every operation on polynomial class class 9 maths chapter 2 question answer free is explained below chaptdr solved examples.
