Simplifying x2 = 4x2 + -15x Reorder the terms: x2 = -15x + 4x2 Solving x2 = -15x + 4x2 Solving for variable 'x'. Reorder the terms: 15x + x2 + -4x2 = -15x + 4x2 + 15x + -4x2 Combine like terms: x2 + -4x2 = -3x2 15x + -3x2 = -15x + 4x2 + 15x + -4x2 Reorder the terms: 15x + -3x2 = -15x + 15x + 4x2 + -4x2 Combine like terms: -15x + 15x = 0 15x + -3x2 = 0 + 4x2 + -4x2 15x + -3x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 15x + -3x2 = 0 Factor out the Greatest Common Factor (GCF), '3x'. 3x(5 + -1x) = 0 Ignore the factor 3.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 '(5 + -1x)' equal to zero and attempt to solve: Simplifying 5 + -1x = 0 Solving 5 + -1x = 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 + -1x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1x = 0 + -5 -1x = 0 + -5 Combine like terms: 0 + -5 = -5 -1x = -5 Divide each side by '-1'. x = 5 Simplifying x = 5Solution
x = {0, 5}
