(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 ]
