Simplifying (2x + -8)(x + 3) = 0 Reorder the terms: (-8 + 2x)(x + 3) = 0 Reorder the terms: (-8 + 2x)(3 + x) = 0 Multiply (-8 + 2x) * (3 + x) (-8(3 + x) + 2x * (3 + x)) = 0 ((3 * -8 + x * -8) + 2x * (3 + x)) = 0 ((-24 + -8x) + 2x * (3 + x)) = 0 (-24 + -8x + (3 * 2x + x * 2x)) = 0 (-24 + -8x + (6x + 2x2)) = 0 Combine like terms: -8x + 6x = -2x (-24 + -2x + 2x2) = 0 Solving -24 + -2x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-12 + -1x + x2) = 0 Factor a trinomial. 2((-3 + -1x)(4 + -1x)) = 0 Ignore the factor 2.Subproblem 1
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 = -3Subproblem 2
Set the factor '(4 + -1x)' equal to zero and attempt to solve: Simplifying 4 + -1x = 0 Solving 4 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x = 0 + -4 -1x = 0 + -4 Combine like terms: 0 + -4 = -4 -1x = -4 Divide each side by '-1'. x = 4 Simplifying x = 4Solution
