Simplifying -3x3 = 5x2 + 2x Reorder the terms: -3x3 = 2x + 5x2 Solving -3x3 = 2x + 5x2 Solving for variable 'x'. Reorder the terms: -2x + -5x2 + -3x3 = 2x + 5x2 + -2x + -5x2 Reorder the terms: -2x + -5x2 + -3x3 = 2x + -2x + 5x2 + -5x2 Combine like terms: 2x + -2x = 0 -2x + -5x2 + -3x3 = 0 + 5x2 + -5x2 -2x + -5x2 + -3x3 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 -2x + -5x2 + -3x3 = 0 Factor out the Greatest Common Factor (GCF), '-1x'. -1x(2 + 5x + 3x2) = 0 Factor a trinomial. -1x((1 + x)(2 + 3x)) = 0 Ignore the factor -1.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
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 3
Set the factor '(2 + 3x)' equal to zero and attempt to solve: Simplifying 2 + 3x = 0 Solving 2 + 3x = 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 + 3x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3x = 0 + -2 3x = 0 + -2 Combine like terms: 0 + -2 = -2 3x = -2 Divide each side by '3'. x = -0.6666666667 Simplifying x = -0.6666666667Solution
x = {0, -1, -0.6666666667}
