Simplifying (x + -2)(x + -6) = -4 Reorder the terms: (-2 + x)(x + -6) = -4 Reorder the terms: (-2 + x)(-6 + x) = -4 Multiply (-2 + x) * (-6 + x) (-2(-6 + x) + x(-6 + x)) = -4 ((-6 * -2 + x * -2) + x(-6 + x)) = -4 ((12 + -2x) + x(-6 + x)) = -4 (12 + -2x + (-6 * x + x * x)) = -4 (12 + -2x + (-6x + x2)) = -4 Combine like terms: -2x + -6x = -8x (12 + -8x + x2) = -4 Solving 12 + -8x + x2 = -4 Solving for variable 'x'. Reorder the terms: 12 + 4 + -8x + x2 = -4 + 4 Combine like terms: 12 + 4 = 16 16 + -8x + x2 = -4 + 4 Combine like terms: -4 + 4 = 0 16 + -8x + x2 = 0 Factor a trinomial. (4 + -1x)(4 + -1x) = 0Subproblem 1
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 = 4Subproblem 2
