Simplifying (x + -1)(x + -1) + -1(x + 4)(x + 4) = -2x + 1 Reorder the terms: (-1 + x)(x + -1) + -1(x + 4)(x + 4) = -2x + 1 Reorder the terms: (-1 + x)(-1 + x) + -1(x + 4)(x + 4) = -2x + 1 Multiply (-1 + x) * (-1 + x) (-1(-1 + x) + x(-1 + x)) + -1(x + 4)(x + 4) = -2x + 1 ((-1 * -1 + x * -1) + x(-1 + x)) + -1(x + 4)(x + 4) = -2x + 1 ((1 + -1x) + x(-1 + x)) + -1(x + 4)(x + 4) = -2x + 1 (1 + -1x + (-1 * x + x * x)) + -1(x + 4)(x + 4) = -2x + 1 (1 + -1x + (-1x + x2)) + -1(x + 4)(x + 4) = -2x + 1 Combine like terms: -1x + -1x = -2x (1 + -2x + x2) + -1(x + 4)(x + 4) = -2x + 1 Reorder the terms: 1 + -2x + x2 + -1(4 + x)(x + 4) = -2x + 1 Reorder the terms: 1 + -2x + x2 + -1(4 + x)(4 + x) = -2x + 1 Multiply (4 + x) * (4 + x) 1 + -2x + x2 + -1(4(4 + x) + x(4 + x)) = -2x + 1 1 + -2x + x2 + -1((4 * 4 + x * 4) + x(4 + x)) = -2x + 1 1 + -2x + x2 + -1((16 + 4x) + x(4 + x)) = -2x + 1 1 + -2x + x2 + -1(16 + 4x + (4 * x + x * x)) = -2x + 1 1 + -2x + x2 + -1(16 + 4x + (4x + x2)) = -2x + 1 Combine like terms: 4x + 4x = 8x 1 + -2x + x2 + -1(16 + 8x + x2) = -2x + 1 1 + -2x + x2 + (16 * -1 + 8x * -1 + x2 * -1) = -2x + 1 1 + -2x + x2 + (-16 + -8x + -1x2) = -2x + 1 Reorder the terms: 1 + -16 + -2x + -8x + x2 + -1x2 = -2x + 1 Combine like terms: 1 + -16 = -15 -15 + -2x + -8x + x2 + -1x2 = -2x + 1 Combine like terms: -2x + -8x = -10x -15 + -10x + x2 + -1x2 = -2x + 1 Combine like terms: x2 + -1x2 = 0 -15 + -10x + 0 = -2x + 1 -15 + -10x = -2x + 1 Reorder the terms: -15 + -10x = 1 + -2x Solving -15 + -10x = 1 + -2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2x' to each side of the equation. -15 + -10x + 2x = 1 + -2x + 2x Combine like terms: -10x + 2x = -8x -15 + -8x = 1 + -2x + 2x Combine like terms: -2x + 2x = 0 -15 + -8x = 1 + 0 -15 + -8x = 1 Add '15' to each side of the equation. -15 + 15 + -8x = 1 + 15 Combine like terms: -15 + 15 = 0 0 + -8x = 1 + 15 -8x = 1 + 15 Combine like terms: 1 + 15 = 16 -8x = 16 Divide each side by '-8'. x = -2 Simplifying x = -2
