Simplifying x2 + -9x2 = 9x Combine like terms: x2 + -9x2 = -8x2 -8x2 = 9x Solving -8x2 = 9x Solving for variable 'x'. Reorder the terms: -9x + -8x2 = 9x + -9x Combine like terms: 9x + -9x = 0 -9x + -8x2 = 0 Factor out the Greatest Common Factor (GCF), '-1x'. -1x(9 + 8x) = 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 '(9 + 8x)' equal to zero and attempt to solve: Simplifying 9 + 8x = 0 Solving 9 + 8x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + 8x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 8x = 0 + -9 8x = 0 + -9 Combine like terms: 0 + -9 = -9 8x = -9 Divide each side by '8'. x = -1.125 Simplifying x = -1.125Solution
x = {0, -1.125}
