Simplifying x2 + -7x = 5x2 + -12x Reorder the terms: -7x + x2 = 5x2 + -12x Reorder the terms: -7x + x2 = -12x + 5x2 Solving -7x + x2 = -12x + 5x2 Solving for variable 'x'. Reorder the terms: -7x + 12x + x2 + -5x2 = -12x + 5x2 + 12x + -5x2 Combine like terms: -7x + 12x = 5x 5x + x2 + -5x2 = -12x + 5x2 + 12x + -5x2 Combine like terms: x2 + -5x2 = -4x2 5x + -4x2 = -12x + 5x2 + 12x + -5x2 Reorder the terms: 5x + -4x2 = -12x + 12x + 5x2 + -5x2 Combine like terms: -12x + 12x = 0 5x + -4x2 = 0 + 5x2 + -5x2 5x + -4x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 5x + -4x2 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(5 + -4x) = 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 '(5 + -4x)' equal to zero and attempt to solve: Simplifying 5 + -4x = 0 Solving 5 + -4x = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -4x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -4x = 0 + -5 -4x = 0 + -5 Combine like terms: 0 + -5 = -5 -4x = -5 Divide each side by '-4'. x = 1.25 Simplifying x = 1.25Solution
x = {0, 1.25}
