Simplifying (x + 2)(x + -9) = x(5 + x) Reorder the terms: (2 + x)(x + -9) = x(5 + x) Reorder the terms: (2 + x)(-9 + x) = x(5 + x) Multiply (2 + x) * (-9 + x) (2(-9 + x) + x(-9 + x)) = x(5 + x) ((-9 * 2 + x * 2) + x(-9 + x)) = x(5 + x) ((-18 + 2x) + x(-9 + x)) = x(5 + x) (-18 + 2x + (-9 * x + x * x)) = x(5 + x) (-18 + 2x + (-9x + x2)) = x(5 + x) Combine like terms: 2x + -9x = -7x (-18 + -7x + x2) = x(5 + x) -18 + -7x + x2 = (5 * x + x * x) -18 + -7x + x2 = (5x + x2) Add '-1x2' to each side of the equation. -18 + -7x + x2 + -1x2 = 5x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -18 + -7x + 0 = 5x + x2 + -1x2 -18 + -7x = 5x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -18 + -7x = 5x + 0 -18 + -7x = 5x Solving -18 + -7x = 5x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5x' to each side of the equation. -18 + -7x + -5x = 5x + -5x Combine like terms: -7x + -5x = -12x -18 + -12x = 5x + -5x Combine like terms: 5x + -5x = 0 -18 + -12x = 0 Add '18' to each side of the equation. -18 + 18 + -12x = 0 + 18 Combine like terms: -18 + 18 = 0 0 + -12x = 0 + 18 -12x = 0 + 18 Combine like terms: 0 + 18 = 18 -12x = 18 Divide each side by '-12'. x = -1.5 Simplifying x = -1.5
