## Important Topics for RS Aggarwal Solutions for Class 10 Maths Chapter 2 polynomials

In this chapter, you will learn about polynomials and types of polynomials. Let us learn the following basic terms:

**Polynomials:**An arithmetical expression in which there is a non-negative integer exponent of variables. These are also called indeterminate.

For example: 6x^{3} -4x^{2} – 2x -1 = polynomial in x variable

These are denoted by k(x), l(x), r (x) etc.

**Coefficients**: any number which helps to get a product with a variable.

For example, in the case of polynomials 6x^{3}-4x^{2} – 2x, the coefficients of 6x^{3}, 4x^{2}, 2x are 2, 4, 6 respectively.

**Terms of polynomials**: these are the important part of any equation separated by plus or minus signs. Every part of the polynomial in the given equations is called the term.

For example, in the polynomial 6x^{3} – 4x^{2} – 2x -1 there are 4 terms.

**Constant polynomial**: when there is only 1 constant term the polynomial is called a constant polynomial.

p(x) = c, where c is any number

**Zero polynomial**: a polynomial in which the polynomial is 0

p(x) = 0

**Binomials**: a polynomial where there are 2 terms.

For example, A(z) = 10x^{2} +z

**Trinomials**: a polynomial having 3 terms.

For example: q(x) = x^{3} -3x +5

**Linear****polynomial**: polynomial having degree 1

For example: 3x -5, s+7 etc.

**Properties of a polynomial:**

**Division Theorem:**p(x) = g(x)*q(x)+ r(x), where p(x) divided by g(x) results in q(x) as quotient and r(x) as a remainder**Remainder Theorem:**p*(a) = r when P(x) / (x-a) leaves remainder ‘r’**Factor Theorem:**p(x) / q(x) = r(x) with 0 remainder only if q(x) is a factor of p(x)

**Polynomial Equation:** it is an equation with constants and variables. A polynomial equation is written in a format where highest degree, all the lower degree and then, at last, the constant term.

For example: p(x) = 4x^{3} + 5x^{2} – 7x + 2 is a polynomial equation.
