Simplifying x2 + 1 = 2(5x + -12) Reorder the terms: 1 + x2 = 2(5x + -12) Reorder the terms: 1 + x2 = 2(-12 + 5x) 1 + x2 = (-12 * 2 + 5x * 2) 1 + x2 = (-24 + 10x) Solving 1 + x2 = -24 + 10x Solving for variable 'x'. Reorder the terms: 1 + 24 + -10x + x2 = -24 + 10x + 24 + -10x Combine like terms: 1 + 24 = 25 25 + -10x + x2 = -24 + 10x + 24 + -10x Reorder the terms: 25 + -10x + x2 = -24 + 24 + 10x + -10x Combine like terms: -24 + 24 = 0 25 + -10x + x2 = 0 + 10x + -10x 25 + -10x + x2 = 10x + -10x Combine like terms: 10x + -10x = 0 25 + -10x + x2 = 0 Factor a trinomial. (5 + -1x)(5 + -1x) = 0Subproblem 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
