Lol i know how it works, we were taught this method afterthe cross multiplication method where you draw a large plus sign then put numbers in side like X^2 + 6 on the bottom left space then the 5x at the bottom right space. then extend upwards.. it should look like....
X + 3 l 3X
X + 2 l 2X
__________
X^2 + 6l 5X
X multiply by X = X^2 and 3 x 2 = 6 then 3X + 2X = 5X.... then the equation transforms into. (X + 3)(X + 2) = 0 then either X + 3 = 0 or X + 2 = 0
Thus X = -2 or -3...
