Simplifying (x + 9)(x + -7) = (2x + 1)(x + -7) Reorder the terms: (9 + x)(x + -7) = (2x + 1)(x + -7) Reorder the terms: (9 + x)(-7 + x) = (2x + 1)(x + -7) Multiply (9 + x) * (-7 + x) (9(-7 + x) + x(-7 + x)) = (2x + 1)(x + -7) ((-7 * 9 + x * 9) + x(-7 + x)) = (2x + 1)(x + -7) ((-63 + 9x) + x(-7 + x)) = (2x + 1)(x + -7) (-63 + 9x + (-7 * x + x * x)) = (2x + 1)(x + -7) (-63 + 9x + (-7x + x2)) = (2x + 1)(x + -7) Combine like terms: 9x + -7x = 2x (-63 + 2x + x2) = (2x + 1)(x + -7) Reorder the terms: -63 + 2x + x2 = (1 + 2x)(x + -7) Reorder the terms: -63 + 2x + x2 = (1 + 2x)(-7 + x) Multiply (1 + 2x) * (-7 + x) -63 + 2x + x2 = (1(-7 + x) + 2x * (-7 + x)) -63 + 2x + x2 = ((-7 * 1 + x * 1) + 2x * (-7 + x)) -63 + 2x + x2 = ((-7 + 1x) + 2x * (-7 + x)) -63 + 2x + x2 = (-7 + 1x + (-7 * 2x + x * 2x)) -63 + 2x + x2 = (-7 + 1x + (-14x + 2x2)) Combine like terms: 1x + -14x = -13x -63 + 2x + x2 = (-7 + -13x + 2x2) Solving -63 + 2x + x2 = -7 + -13x + 2x2 Solving for variable 'x'. Reorder the terms: -63 + 7 + 2x + 13x + x2 + -2x2 = -7 + -13x + 2x2 + 7 + 13x + -2x2 Combine like terms: -63 + 7 = -56 -56 + 2x + 13x + x2 + -2x2 = -7 + -13x + 2x2 + 7 + 13x + -2x2 Combine like terms: 2x + 13x = 15x -56 + 15x + x2 + -2x2 = -7 + -13x + 2x2 + 7 + 13x + -2x2 Combine like terms: x2 + -2x2 = -1x2 -56 + 15x + -1x2 = -7 + -13x + 2x2 + 7 + 13x + -2x2 Reorder the terms: -56 + 15x + -1x2 = -7 + 7 + -13x + 13x + 2x2 + -2x2 Combine like terms: -7 + 7 = 0 -56 + 15x + -1x2 = 0 + -13x + 13x + 2x2 + -2x2 -56 + 15x + -1x2 = -13x + 13x + 2x2 + -2x2 Combine like terms: -13x + 13x = 0 -56 + 15x + -1x2 = 0 + 2x2 + -2x2 -56 + 15x + -1x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -56 + 15x + -1x2 = 0 Factor a trinomial. (-8 + x)(7 + -1x) = 0Subproblem 1
Set the factor '(-8 + x)' equal to zero and attempt to solve: Simplifying -8 + x = 0 Solving -8 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + x = 0 + 8 Combine like terms: -8 + 8 = 0 0 + x = 0 + 8 x = 0 + 8 Combine like terms: 0 + 8 = 8 x = 8 Simplifying x = 8Subproblem 2
Set the factor '(7 + -1x)' equal to zero and attempt to solve: Simplifying 7 + -1x = 0 Solving 7 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1x = 0 + -7 -1x = 0 + -7 Combine like terms: 0 + -7 = -7 -1x = -7 Divide each side by '-1'. x = 7 Simplifying x = 7Solution
x = {8, 7}
