Answer:
After that, we will see the plot of the polynomial and verify our answer. ... In the above figure, the curve $y={{x}^{2}}+x-2$ intersects the x-axis at two points A (-2,0) and B (1,0) and it is evident that ${{x}^{2}}+x-2$ is the quadratic polynomial having zeros 1 and -2.
hope it's help you!!!
