4x2 - 2x - 12
= 2x2 - x - 6
= 2x2 - 4x + 3x - 6
= 2x(x - 2) + 3(x - 2)
= (x - 2)(2x + 3)

Factor the equation and solve for x in each part. x3-4x2-12x Factor out an x right away x (x² - 4x - 12) factor the trinomial x (x - 6) (x + 2) now solve each for y=0 x=0, (x-6=0), (x+2=0) The zeroes (solutions) to the equation are {-2 0 6 }■
16 - a2
So the problem is: Solve: 4x2 - x = 3
4x2 - 9 = (2x + 3)(2x - 3)
use the difference of two squares yule.
