Question

find the number of zeros of curve y=p(x)​

Answer 1

Answer:

For any quadratic polynomial ax² +bx+c the zeroes are precisely the x coordinates of the points where the graph of y = ax² + bx+c intersects the X axis.

It is Clear from the graph that curve intersect the x-axis at 3 points. Hence the number of zeros of the polynomial y = p(x) are three.
