## NCERT Solutions for Class 10 Maths Chapter 2 Polynomials Exercise 2.1

Question 1.

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

Solution:

(i) No. of zeroes of p(x) is zero because the graph does not intersect x-axis point.

(ii) No. of zeroes of p(x) is 1 as the graph intersects the x-axis at one point only.

(iii) No. of zeroes p(x) is 3 as the graph intersects x-axis at three points.

(iv) No. of zeroes p(x) is as the graphs intersects the x-axis at two points.

(v) No. of zeroes p(x) is 4 as the graph intersects x-axis at four points.

(vi) No. of zeroes p(x) is 3 as the graph intersects the x-axis at three points.
