Simplifying 2x2 = 8x + 90 Reorder the terms: 2x2 = 90 + 8x Solving 2x2 = 90 + 8x Solving for variable 'x'. Reorder the terms: -90 + -8x + 2x2 = 90 + 8x + -90 + -8x Reorder the terms: -90 + -8x + 2x2 = 90 + -90 + 8x + -8x Combine like terms: 90 + -90 = 0 -90 + -8x + 2x2 = 0 + 8x + -8x -90 + -8x + 2x2 = 8x + -8x Combine like terms: 8x + -8x = 0 -90 + -8x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-45 + -4x + x2) = 0 Factor a trinomial. 2((-5 + -1x)(9 + -1x)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-5 + -1x)' equal to zero and attempt to solve: Simplifying -5 + -1x = 0 Solving -5 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + -1x = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -1x = 0 + 5 -1x = 0 + 5 Combine like terms: 0 + 5 = 5 -1x = 5 Divide each side by '-1'. x = -5 Simplifying x = -5Subproblem 2
Set the factor '(9 + -1x)' equal to zero and attempt to solve: Simplifying 9 + -1x = 0 Solving 9 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1x = 0 + -9 -1x = 0 + -9 Combine like terms: 0 + -9 = -9 -1x = -9 Divide each side by '-1'. x = 9 Simplifying x = 9Solution
x = {-5, 9}
