Simplifying (-9x) * x(-7) = 63x Remove parenthesis around (-9x) -9x * x(-7) = 63x Reorder the terms for easier multiplication: -9 * -7x * x = 63x Multiply -9 * -7 63x * x = 63x Multiply x * x 63x2 = 63x Solving 63x2 = 63x Solving for variable 'x'. Reorder the terms: -63x + 63x2 = 63x + -63x Combine like terms: 63x + -63x = 0 -63x + 63x2 = 0 Factor out the Greatest Common Factor (GCF), '63x'. 63x(-1 + x) = 0 Ignore the factor 63.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 '(-1 + x)' equal to zero and attempt to solve: Simplifying -1 + x = 0 Solving -1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + x = 0 + 1 x = 0 + 1 Combine like terms: 0 + 1 = 1 x = 1 Simplifying x = 1Solution
x = {0, 1}
