Simplifying 3x3 = -7x2 + 6x Reorder the terms: 3x3 = 6x + -7x2 Solving 3x3 = 6x + -7x2 Solving for variable 'x'. Reorder the terms: -6x + 7x2 + 3x3 = 6x + -7x2 + -6x + 7x2 Reorder the terms: -6x + 7x2 + 3x3 = 6x + -6x + -7x2 + 7x2 Combine like terms: 6x + -6x = 0 -6x + 7x2 + 3x3 = 0 + -7x2 + 7x2 -6x + 7x2 + 3x3 = -7x2 + 7x2 Combine like terms: -7x2 + 7x2 = 0 -6x + 7x2 + 3x3 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(-6 + 7x + 3x2) = 0 Factor a trinomial. x((-3 + -1x)(2 + -3x)) = 0Subproblem 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 '(-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 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, -3, 0.6666666667}
