Simplifying (1 + -2x)(1 + -3x) = (6x + -1) * x + -1 Multiply (1 + -2x) * (1 + -3x) (1(1 + -3x) + -2x * (1 + -3x)) = (6x + -1) * x + -1 ((1 * 1 + -3x * 1) + -2x * (1 + -3x)) = (6x + -1) * x + -1 ((1 + -3x) + -2x * (1 + -3x)) = (6x + -1) * x + -1 (1 + -3x + (1 * -2x + -3x * -2x)) = (6x + -1) * x + -1 (1 + -3x + (-2x + 6x2)) = (6x + -1) * x + -1 Combine like terms: -3x + -2x = -5x (1 + -5x + 6x2) = (6x + -1) * x + -1 Reorder the terms: 1 + -5x + 6x2 = (-1 + 6x) * x + -1 Reorder the terms for easier multiplication: 1 + -5x + 6x2 = x(-1 + 6x) + -1 1 + -5x + 6x2 = (-1 * x + 6x * x) + -1 1 + -5x + 6x2 = (-1x + 6x2) + -1 Reorder the terms: 1 + -5x + 6x2 = -1 + -1x + 6x2 Add '-6x2' to each side of the equation. 1 + -5x + 6x2 + -6x2 = -1 + -1x + 6x2 + -6x2 Combine like terms: 6x2 + -6x2 = 0 1 + -5x + 0 = -1 + -1x + 6x2 + -6x2 1 + -5x = -1 + -1x + 6x2 + -6x2 Combine like terms: 6x2 + -6x2 = 0 1 + -5x = -1 + -1x + 0 1 + -5x = -1 + -1x Solving 1 + -5x = -1 + -1x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'x' to each side of the equation. 1 + -5x + x = -1 + -1x + x Combine like terms: -5x + x = -4x 1 + -4x = -1 + -1x + x Combine like terms: -1x + x = 0 1 + -4x = -1 + 0 1 + -4x = -1 Add '-1' to each side of the equation. 1 + -1 + -4x = -1 + -1 Combine like terms: 1 + -1 = 0 0 + -4x = -1 + -1 -4x = -1 + -1 Combine like terms: -1 + -1 = -2 -4x = -2 Divide each side by '-4'. x = 0.5 Simplifying x = 0.5
