Simplifying (2x)(x + 7) = 520 Remove parenthesis around (2x) 2x(x + 7) = 520 Reorder the terms: 2x(7 + x) = 520 (7 * 2x + x * 2x) = 520 (14x + 2x2) = 520 Solving 14x + 2x2 = 520 Solving for variable 'x'. Reorder the terms: -520 + 14x + 2x2 = 520 + -520 Combine like terms: 520 + -520 = 0 -520 + 14x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-260 + 7x + x2) = 0 Factor a trinomial. 2((-20 + -1x)(13 + -1x)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-20 + -1x)' equal to zero and attempt to solve: Simplifying -20 + -1x = 0 Solving -20 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '20' to each side of the equation. -20 + 20 + -1x = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -1x = 0 + 20 -1x = 0 + 20 Combine like terms: 0 + 20 = 20 -1x = 20 Divide each side by '-1'. x = -20 Simplifying x = -20Subproblem 2
Set the factor '(13 + -1x)' equal to zero and attempt to solve: Simplifying 13 + -1x = 0 Solving 13 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + -1x = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -1x = 0 + -13 -1x = 0 + -13 Combine like terms: 0 + -13 = -13 -1x = -13 Divide each side by '-1'. x = 13 Simplifying x = 13Solution
x = {-20, 13}
