SOLUTION: Y=-4x to the 2 power + 12x -8

Question 849805: Y=-4x to the 2 power + 12x -8
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
y = -4x^2 + 12x - 8
set the equation equal to 0 to get:
-4x^2 + 12x - 8 = 0
factor out a -1 to get:
(-1) * (4x^2 - 12x + 8) = 0
this allows the x^2 term to be positive which makes factoring a lot easier.
