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

**Question 1.
**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.

**Solution:**

**(i)** Graph y = p(x) does not intersect the x-axis.

Hence, p(x) has no zero of p(x).

**(ii)** Graph y = p(x) intersects the x-axis at only one point.

Hence, there is only one real zero of p(x).

**(iii)** Graph y = p(x) intersects the x-axis at three points.

Hence, there are three real zeroes of p(x).

**(iv)** Graph y = p(x) intersects the x-axis at two points.

Hence, there are two real zeroes of p(x).

**(v)** Graph y = p(x) intersects the x-axis at four points.

Hence, there are four real zeroes of p(x).

**(vi)** Graph y = p(x) intersects the x-axis at three points.

Hence, there are three real zeroes of p(x).
