RBSE Class 10 Maths Solutions Chapter 2 Polynomials Exercise 2.1
Question 1.
The graphs of y = p(x) are given in Fig. below, for some polynomials p(x). Find the number of zeroes of p(x), in each case.
Solution:
(i) Here these are no zeroes as the graph does not intersect the x-axis.
(ii) Here the number of zeroes is 1 as the graph intersects the x-axis at one point only.
(iii) Here the number of zeroes is 3 as the graph intersects the x-axis at three points only.
(iv) Here the number of zeroes is 2 as the graph intersects the x-axis at two points only.
(v) Here the number of zeroes is 4 as the graph intersects the x-axis at four points only.
(vi) Here the number of zeroes is 3 as the graph intersects the x-axis at three points only.
