Simplifying x2 + 10x + 13 = 4x + 4 Reorder the terms: 13 + 10x + x2 = 4x + 4 Reorder the terms: 13 + 10x + x2 = 4 + 4x Solving 13 + 10x + x2 = 4 + 4x Solving for variable 'x'. Reorder the terms: 13 + -4 + 10x + -4x + x2 = 4 + 4x + -4 + -4x Combine like terms: 13 + -4 = 9 9 + 10x + -4x + x2 = 4 + 4x + -4 + -4x Combine like terms: 10x + -4x = 6x 9 + 6x + x2 = 4 + 4x + -4 + -4x Reorder the terms: 9 + 6x + x2 = 4 + -4 + 4x + -4x Combine like terms: 4 + -4 = 0 9 + 6x + x2 = 0 + 4x + -4x 9 + 6x + x2 = 4x + -4x Combine like terms: 4x + -4x = 0 9 + 6x + x2 = 0 Factor a trinomial. (3 + x)(3 + x) = 0Subproblem 1
Set the factor '(3 + x)' equal to zero and attempt to solve: Simplifying 3 + x = 0 Solving 3 + x = 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 + x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + x = 0 + -3 x = 0 + -3 Combine like terms: 0 + -3 = -3 x = -3 Simplifying x = -3Subproblem 2
