Simplifying (2x + 13)(2x + -13) = 4x + -169 Reorder the terms: (13 + 2x)(2x + -13) = 4x + -169 Reorder the terms: (13 + 2x)(-13 + 2x) = 4x + -169 Multiply (13 + 2x) * (-13 + 2x) (13(-13 + 2x) + 2x * (-13 + 2x)) = 4x + -169 ((-13 * 13 + 2x * 13) + 2x * (-13 + 2x)) = 4x + -169 ((-169 + 26x) + 2x * (-13 + 2x)) = 4x + -169 (-169 + 26x + (-13 * 2x + 2x * 2x)) = 4x + -169 (-169 + 26x + (-26x + 4x2)) = 4x + -169 Combine like terms: 26x + -26x = 0 (-169 + 0 + 4x2) = 4x + -169 (-169 + 4x2) = 4x + -169 Reorder the terms: -169 + 4x2 = -169 + 4x Add '169' to each side of the equation. -169 + 169 + 4x2 = -169 + 169 + 4x Combine like terms: -169 + 169 = 0 0 + 4x2 = -169 + 169 + 4x 4x2 = -169 + 169 + 4x Combine like terms: -169 + 169 = 0 4x2 = 0 + 4x 4x2 = 4x Solving 4x2 = 4x Solving for variable 'x'. Reorder the terms: -4x + 4x2 = 4x + -4x Combine like terms: 4x + -4x = 0 -4x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '4x'. 4x(-1 + x) = 0 Ignore the factor 4.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}
