Class 10 Maths Important Questions for Polynomial



In this page we have NCERT book Solutions for Class 10th Maths:Polynomials for EXERCISE 1 . Hope you like them and do not forget to like , social_share and comment at the end of the page.
The graphs of y = p(x) are given below, for some polynomials p(x). Find the
number of zeroes of p(x), in each case.

iii)

iv)

v)

vi)

Solution:
The zero’s of the polynomial are the points  where the graph meet x axis in the Cartesian plane. If the graph does not meet x axis ,then the polynomial does not have any zero’s.
  1.  Since it does not intersect x-axis ,it does not have any zero’s
  2. Since it intersect x-axis once ,it has one zero
  3. Since it intersect the x-axis thrice,it has three zero’s
  4. Since it intersect the x-axis two,it has two zero’s
  5. Since it intersect the x-axis four times,it has four zero’s
  6. Since it intersect the x-axis thrice,it has three zero’s
