Learn all Concepts of Polynomials Class 9 (with VIDEOS). Check - Polynomials Class 9           Equations of the type

x 3 − 3x 2 + 4x + 10

are called polynomials.

Here,

x 3 , −3x 2 , 4x , 10 are called terms of polynomials.

A Polynomial has

• Variables like x, y with powers as whole numbers (0, 1, 2, 3, ....). If Power is not a whole number , the equation is not a polynomial.
• constants like 10

## Polynomial in one variable

In this chapter,

We will be studying polynomials which are in one variable, i.e. only has x or y, but not both.

Example - x 2 + 2x - 3 is a polynomial in one variable as there is only x

But x 2 + 2y - 3x = 0 is not a polynomial in one variable as there is both x and y.

Is x 2 + 24y + 1 a  polynomial in one variable?

Is y 4 – 10 a polynomial in one variable?

Is 5x -2 + 1 a polynomial in one variable?

Is  3x 1/2 + 2 a polynomial in one variable?

Is 3 a polynomial in one variable?

Note:

Constant numbers are also polynomials.

Example: 2, 3, 100, -988999 are all polynomials
