Simplifying x2 + 5x + -6 = 2x2 + -1x + -1 Reorder the terms: -6 + 5x + x2 = 2x2 + -1x + -1 Reorder the terms: -6 + 5x + x2 = -1 + -1x + 2x2 Solving -6 + 5x + x2 = -1 + -1x + 2x2 Solving for variable 'x'. Reorder the terms: -6 + 1 + 5x + x + x2 + -2x2 = -1 + -1x + 2x2 + 1 + x + -2x2 Combine like terms: -6 + 1 = -5 -5 + 5x + x + x2 + -2x2 = -1 + -1x + 2x2 + 1 + x + -2x2 Combine like terms: 5x + x = 6x -5 + 6x + x2 + -2x2 = -1 + -1x + 2x2 + 1 + x + -2x2 Combine like terms: x2 + -2x2 = -1x2 -5 + 6x + -1x2 = -1 + -1x + 2x2 + 1 + x + -2x2 Reorder the terms: -5 + 6x + -1x2 = -1 + 1 + -1x + x + 2x2 + -2x2 Combine like terms: -1 + 1 = 0 -5 + 6x + -1x2 = 0 + -1x + x + 2x2 + -2x2 -5 + 6x + -1x2 = -1x + x + 2x2 + -2x2 Combine like terms: -1x + x = 0 -5 + 6x + -1x2 = 0 + 2x2 + -2x2 -5 + 6x + -1x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -5 + 6x + -1x2 = 0 Factor a trinomial. (-5 + x)(1 + -1x) = 0Subproblem 1
Set the factor '(-5 + x)' equal to zero and attempt to solve: Simplifying -5 + x = 0 Solving -5 + x = 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 + x = 0 + 5 Combine like terms: -5 + 5 = 0 0 + x = 0 + 5 x = 0 + 5 Combine like terms: 0 + 5 = 5 x = 5 Simplifying x = 5Subproblem 2
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 = 1Solution
x = {5, 1}
