Simplifying (x + 4) * x = (x + -5)(x + -1) Reorder the terms: (4 + x) * x = (x + -5)(x + -1) Reorder the terms for easier multiplication: x(4 + x) = (x + -5)(x + -1) (4 * x + x * x) = (x + -5)(x + -1) (4x + x2) = (x + -5)(x + -1) Reorder the terms: 4x + x2 = (-5 + x)(x + -1) Reorder the terms: 4x + x2 = (-5 + x)(-1 + x) Multiply (-5 + x) * (-1 + x) 4x + x2 = (-5(-1 + x) + x(-1 + x)) 4x + x2 = ((-1 * -5 + x * -5) + x(-1 + x)) 4x + x2 = ((5 + -5x) + x(-1 + x)) 4x + x2 = (5 + -5x + (-1 * x + x * x)) 4x + x2 = (5 + -5x + (-1x + x2)) Combine like terms: -5x + -1x = -6x 4x + x2 = (5 + -6x + x2) Add '-1x2' to each side of the equation. 4x + x2 + -1x2 = 5 + -6x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 4x + 0 = 5 + -6x + x2 + -1x2 4x = 5 + -6x + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 4x = 5 + -6x + 0 4x = 5 + -6x Solving 4x = 5 + -6x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6x' to each side of the equation. 4x + 6x = 5 + -6x + 6x Combine like terms: 4x + 6x = 10x 10x = 5 + -6x + 6x Combine like terms: -6x + 6x = 0 10x = 5 + 0 10x = 5 Divide each side by '10'. x = 0.5 Simplifying x = 0.5
