Simplifying 0 = -16x2 + 64x + -48 Reorder the terms: 0 = -48 + 64x + -16x2 Solving 0 = -48 + 64x + -16x2 Solving for variable 'x'. Combine like terms: 0 + 48 = 48 48 + -64x + 16x2 = -48 + 64x + -16x2 + 48 + -64x + 16x2 Reorder the terms: 48 + -64x + 16x2 = -48 + 48 + 64x + -64x + -16x2 + 16x2 Combine like terms: -48 + 48 = 0 48 + -64x + 16x2 = 0 + 64x + -64x + -16x2 + 16x2 48 + -64x + 16x2 = 64x + -64x + -16x2 + 16x2 Combine like terms: 64x + -64x = 0 48 + -64x + 16x2 = 0 + -16x2 + 16x2 48 + -64x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 48 + -64x + 16x2 = 0 Factor out the Greatest Common Factor (GCF), '16'. 16(3 + -4x + x2) = 0 Factor a trinomial. 16((1 + -1x)(3 + -1x)) = 0 Ignore the factor 16.Subproblem 1
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1Subproblem 2
Set the factor '(3 + -1x)' equal to zero and attempt to solve: Simplifying 3 + -1x = 0 Solving 3 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1x = 0 + -3 -1x = 0 + -3 Combine like terms: 0 + -3 = -3 -1x = -3 Divide each side by '-1'. x = 3 Simplifying x = 3Solution
