The solutions are:
$color(green)(x=-2, x=1$

$color(green)((x+2)(x-1) = 0$ , is the factorised form of the equation
$x^2+x-2=0$

Whenever we have factors of an equation we need to equate each of the factors with zero to find the solutions:

So,
$x+2 = 0 , x=-2$
$x-1 = 0, x=1$

So the solutions are:
$color(green)(x=-2, x=1$

How do you solve (x+2)(x-1)= 0(x+2)(x-1)= 0?
