So its just expanding right?
x^2+2x+3x+6
= x^2+5x+6

Evaluate?
(x+3)(x+2)= 0
answer:
x= -3, -2
Expand?
(x+3)(x+2)
answer:
x^2+5x+6
Quadratic Inequality?
(x+3)(x+2) ≤ 0
answer:
x=-3
x=-2
(-3,-2) : two parentheses are actually supposed to be brackets. because -3,-2 are both solutions.

use FOIL method or first , outer, inner, and last
it's like this if you don't use the FOIL method
x(x+2) + 3(x+2)
x^2+2x+3x+6
which gives you x^2+5x+6
