I'll help you out with the first one.
first, set it as an equality
(x+2)(x-3) = 0
so this means
x + 2 = 0 or x - 3 = 0
x = -2
x = 3
now, line graph
<---(-2)-------(0)-------------(3)--------->
and test out each area (so... pick -3, -1, 1, and 4), and plug in back into equation, and see if it's negative.
