Simplifying 47x2 + -80x = 7x2 Reorder the terms: -80x + 47x2 = 7x2 Solving -80x + 47x2 = 7x2 Solving for variable 'x'. Combine like terms: 47x2 + -7x2 = 40x2 -80x + 40x2 = 7x2 + -7x2 Combine like terms: 7x2 + -7x2 = 0 -80x + 40x2 = 0 Factor out the Greatest Common Factor (GCF), '40x'. 40x(-2 + x) = 0 Ignore the factor 40.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}
