Simplifying 3x2 + -1x + 3 = -7x Reorder the terms: 3 + -1x + 3x2 = -7x Solving 3 + -1x + 3x2 = -7x Solving for variable 'x'. Reorder the terms: 3 + -1x + 7x + 3x2 = -7x + 7x Combine like terms: -1x + 7x = 6x 3 + 6x + 3x2 = -7x + 7x Combine like terms: -7x + 7x = 0 3 + 6x + 3x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(1 + 2x + x2) = 0 Factor a trinomial. 3((1 + x)(1 + x)) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 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 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1Subproblem 2
