The graph of $y = x^{2} + x - 2$ is shown, cutting the $x$ -axis at two points.
Read off the zeroes of the polynomial from the graph.

Class 10Zeroes and CoefficientsAlgebra — Polynomials

A1 and -2
B-1 and 2
C1 and 2
D-1 and -2

Step-by-Step Solution

x^{2} + x - 2 = (x - 1) (x + 2)

, so the curve crosses the

x

-axis at

x = 1

and

x = - 2

.

Answer: A) 1 and -2
