Simplifying x2 + -9x + 20 = (x + -4)(x + 5) Reorder the terms: 20 + -9x + x2 = (x + -4)(x + 5) Reorder the terms: 20 + -9x + x2 = (-4 + x)(x + 5) Reorder the terms: 20 + -9x + x2 = (-4 + x)(5 + x) Multiply (-4 + x) * (5 + x) 20 + -9x + x2 = (-4(5 + x) + x(5 + x)) 20 + -9x + x2 = ((5 * -4 + x * -4) + x(5 + x)) 20 + -9x + x2 = ((-20 + -4x) + x(5 + x)) 20 + -9x + x2 = (-20 + -4x + (5 * x + x * x)) 20 + -9x + x2 = (-20 + -4x + (5x + x2)) Combine like terms: -4x + 5x = 1x 20 + -9x + x2 = (-20 + 1x + x2) Add '-1x2' to each side of the equation. 20 + -9x + x2 + -1x2 = -20 + 1x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 20 + -9x + 0 = -20 + 1x + x2 + -1x2 20 + -9x = -20 + 1x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 20 + -9x = -20 + 1x + 0 20 + -9x = -20 + 1x Solving 20 + -9x = -20 + 1x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x' to each side of the equation. 20 + -9x + -1x = -20 + 1x + -1x Combine like terms: -9x + -1x = -10x 20 + -10x = -20 + 1x + -1x Combine like terms: 1x + -1x = 0 20 + -10x = -20 + 0 20 + -10x = -20 Add '-20' to each side of the equation. 20 + -20 + -10x = -20 + -20 Combine like terms: 20 + -20 = 0 0 + -10x = -20 + -20 -10x = -20 + -20 Combine like terms: -20 + -20 = -40 -10x = -40 Divide each side by '-10'. x = 4 Simplifying x = 4
