Simplifying (x + 7)(x + 10) = 130 Reorder the terms: (7 + x)(x + 10) = 130 Reorder the terms: (7 + x)(10 + x) = 130 Multiply (7 + x) * (10 + x) (7(10 + x) + x(10 + x)) = 130 ((10 * 7 + x * 7) + x(10 + x)) = 130 ((70 + 7x) + x(10 + x)) = 130 (70 + 7x + (10 * x + x * x)) = 130 (70 + 7x + (10x + x2)) = 130 Combine like terms: 7x + 10x = 17x (70 + 17x + x2) = 130 Solving 70 + 17x + x2 = 130 Solving for variable 'x'. Reorder the terms: 70 + -130 + 17x + x2 = 130 + -130 Combine like terms: 70 + -130 = -60 -60 + 17x + x2 = 130 + -130 Combine like terms: 130 + -130 = 0 -60 + 17x + x2 = 0 Factor a trinomial. (-20 + -1x)(3 + -1x) = 0Subproblem 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 '(3 + -1x)' equal to zero and attempt to solve: Simplifying 3 + -1x = 0 Solving 3 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1x = 0 + -3 -1x = 0 + -3 Combine like terms: 0 + -3 = -3 -1x = -3 Divide each side by '-1'. x = 3 Simplifying x = 3Solution
x = {-20, 3}
