Simplifying 5x2 = 30x + -10x2 Solving 5x2 = 30x + -10x2 Solving for variable 'x'. Reorder the terms: -30x + 5x2 + 10x2 = 30x + -10x2 + -30x + 10x2 Combine like terms: 5x2 + 10x2 = 15x2 -30x + 15x2 = 30x + -10x2 + -30x + 10x2 Reorder the terms: -30x + 15x2 = 30x + -30x + -10x2 + 10x2 Combine like terms: 30x + -30x = 0 -30x + 15x2 = 0 + -10x2 + 10x2 -30x + 15x2 = -10x2 + 10x2 Combine like terms: -10x2 + 10x2 = 0 -30x + 15x2 = 0 Factor out the Greatest Common Factor (GCF), '15x'. 15x(-2 + x) = 0 Ignore the factor 15.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 '(-2 + x)' equal to zero and attempt to solve: Simplifying -2 + x = 0 Solving -2 + x = 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 + x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + x = 0 + 2 x = 0 + 2 Combine like terms: 0 + 2 = 2 x = 2 Simplifying x = 2Solution
x = {0, 2}
