The GCF is 4x.

gcf(12x, 18x²) = 6x

144x2 - 25

If that were + 35, it would factor to (x + 5)(x + 7) As it is, it doesn't factor neatly. Applying the quadratic formula, we find two real solutions: -6 plus or minus the square root of 71 x = 2.426149773176359 x = -14.426149773176359

x2_12x-3 = 0 Using the formula for solving quadratics: x = 12 plus/minus sqrt (144 - (4 x 1 x -3))/2 x = 12 plus/minus (sqrt 156)/2 x = 12 + (sqrt 156)/2 = 12.25 or x = 12 - (sqrt 156)/2 = -0.25
