(x + 2) ( x - 3) ≤ 0

Let's solve this

( x + 2) ( x - 3) = 0

Set both factors to 0 and solve for x and we get that x = - 2 or x = 3

The solutions will come from ( - inf, -2) or [-2, 3 ] or ( 3, inf )

Note that if we pick a point in [ -2, 3] (say, 0)....it will make the original inequality true

And the other two intervals will not make the inequality true

So...the solution is [ -2, 3 ]
