Simplifying x2 + x + -2 = x + 4 + -1x Reorder the terms: -2 + x + x2 = x + 4 + -1x Reorder the terms: -2 + x + x2 = 4 + x + -1x Combine like terms: x + -1x = 0 -2 + x + x2 = 4 + 0 -2 + x + x2 = 4 Solving -2 + x + x2 = 4 Solving for variable 'x'. Reorder the terms: -2 + -4 + x + x2 = 4 + -4 Combine like terms: -2 + -4 = -6 -6 + x + x2 = 4 + -4 Combine like terms: 4 + -4 = 0 -6 + x + x2 = 0 Factor a trinomial. (-3 + -1x)(2 + -1x) = 0Subproblem 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 '(2 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Divide each side by '-1'. x = 2 Simplifying x = 2Solution
x = {-3, 2}
