Simplifying -31x2 + -11x = -7x2 + -3x Reorder the terms: -11x + -31x2 = -7x2 + -3x Reorder the terms: -11x + -31x2 = -3x + -7x2 Solving -11x + -31x2 = -3x + -7x2 Solving for variable 'x'. Reorder the terms: -11x + 3x + -31x2 + 7x2 = -3x + -7x2 + 3x + 7x2 Combine like terms: -11x + 3x = -8x -8x + -31x2 + 7x2 = -3x + -7x2 + 3x + 7x2 Combine like terms: -31x2 + 7x2 = -24x2 -8x + -24x2 = -3x + -7x2 + 3x + 7x2 Reorder the terms: -8x + -24x2 = -3x + 3x + -7x2 + 7x2 Combine like terms: -3x + 3x = 0 -8x + -24x2 = 0 + -7x2 + 7x2 -8x + -24x2 = -7x2 + 7x2 Combine like terms: -7x2 + 7x2 = 0 -8x + -24x2 = 0 Factor out the Greatest Common Factor (GCF), '-8x'. -8x(1 + 3x) = 0 Ignore the factor -8.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 + 3x)' equal to zero and attempt to solve: Simplifying 1 + 3x = 0 Solving 1 + 3x = 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 + 3x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3x = 0 + -1 3x = 0 + -1 Combine like terms: 0 + -1 = -1 3x = -1 Divide each side by '3'. x = -0.3333333333 Simplifying x = -0.3333333333Solution
x = {0, -0.3333333333}
