Simplifying (x + 2)(x + 5) = 28 Reorder the terms: (2 + x)(x + 5) = 28 Reorder the terms: (2 + x)(5 + x) = 28 Multiply (2 + x) * (5 + x) (2(5 + x) + x(5 + x)) = 28 ((5 * 2 + x * 2) + x(5 + x)) = 28 ((10 + 2x) + x(5 + x)) = 28 (10 + 2x + (5 * x + x * x)) = 28 (10 + 2x + (5x + x2)) = 28 Combine like terms: 2x + 5x = 7x (10 + 7x + x2) = 28 Solving 10 + 7x + x2 = 28 Solving for variable 'x'. Reorder the terms: 10 + -28 + 7x + x2 = 28 + -28 Combine like terms: 10 + -28 = -18 -18 + 7x + x2 = 28 + -28 Combine like terms: 28 + -28 = 0 -18 + 7x + x2 = 0 Factor a trinomial. (-9 + -1x)(2 + -1x) = 0Subproblem 1
Set the factor '(-9 + -1x)' equal to zero and attempt to solve: Simplifying -9 + -1x = 0 Solving -9 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -1x = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1x = 0 + 9 -1x = 0 + 9 Combine like terms: 0 + 9 = 9 -1x = 9 Divide each side by '-1'. x = -9 Simplifying x = -9Subproblem 2
Set the factor '(2 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 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 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Divide each side by '-1'. x = 2 Simplifying x = 2Solution
x = {-9, 2}
