Important Topics For Xam Idea Class 10 Maths Solutions Chapter 2: Polynomials



  1. In order to define the degree of a polynomial, you can consider p(x) as a polynomial that is the highest power of the variable x.
  2. A Linear polynomial is the one that has the highest power as 1 of the variable.
  3. A quadratic polynomial is the one that has the highest power as 2 of a particular variable.
  4. A cubic polynomial is the one that has the highest power of 3 of the variable.
  5. If you consider p(x) as a polynomial and k to be a real number, then if you would find the value of p(x) by replacing the x with k, then the value of the polynomial, p(x) at x=k will be denoted as p(k).


Zeroes of a Polynomial

Let us understand this with the help of an example,

If p(x) is replaced by p(k), and the real number obtained is p(k)=0, then the k term is known as the zero of a polynomial p(x).


Geometric Representation of Polynomials

  1. The output of a linear polynomial is a straight line graph that intersects the x-axis at one point.
  2. If you will draw the graph of any quadratic equation, you will get an output as a downward or upward-facing parabola that depends on the coefficient of x2.
  3. Also, you will know with the graphical representations that cubic polynomials contain a maximum of 3 zeroes.

Zeroes and Coefficients of a Polynomial

If you Consider a cubic polynomial ax3 + bx2 + cx + d with the zeroes as a ,ß, and ϒ, then the equations are:

Division Algorithm for Polynomials

Suppose, there are two types of polynomials, p(x) and g(x), such that, g(x) 0. 

It is then possible to find the values for polynomials r(x) and q(x) such that:


Where r(x)=0or degree of r(x)< degree of g(x).

In the chapter, you will study all these topics in detail along with some descriptive examples that will help you ace the board exams.
