## NCERT Class 10th Maths Solutions Chapter 2 Polynomials Ex 2.1

Question 1.

The graphs of y = p(x) are given in the below figures, for some polynomials p(x). Find the number of zeroes of p{x), in each case.

Solution:

(i) The given graph is parallel to x-axis, it does not intersect the x-axis.

It has no zero.

(ii) The given graph intersects the x-axis at one point only.

∴ It has one zero.

(iii) The given graph intersects the x-axis at three points.

∴ It has three zeroes.

(iv) The given graph intersects the x-axis at two points.

∴ It has two zeroes.

(v) The given graph intersects the x-axis at four points.

∴ It has four zeroes.

(vi) The given graph meets the x-axis at three points.

∴ It has three zeroes.
