Simplifying y = (x + 1)(x + -2)(x + -4) Reorder the terms: y = (1 + x)(x + -2)(x + -4) Reorder the terms: y = (1 + x)(-2 + x)(x + -4) Reorder the terms: y = (1 + x)(-2 + x)(-4 + x) Multiply (1 + x) * (-2 + x) y = (1(-2 + x) + x(-2 + x))(-4 + x) y = ((-2 * 1 + x * 1) + x(-2 + x))(-4 + x) y = ((-2 + 1x) + x(-2 + x))(-4 + x) y = (-2 + 1x + (-2 * x + x * x))(-4 + x) y = (-2 + 1x + (-2x + x2))(-4 + x) Combine like terms: 1x + -2x = -1x y = (-2 + -1x + x2)(-4 + x) Multiply (-2 + -1x + x2) * (-4 + x) y = (-2(-4 + x) + -1x * (-4 + x) + x2(-4 + x)) y = ((-4 * -2 + x * -2) + -1x * (-4 + x) + x2(-4 + x)) y = ((8 + -2x) + -1x * (-4 + x) + x2(-4 + x)) y = (8 + -2x + (-4 * -1x + x * -1x) + x2(-4 + x)) y = (8 + -2x + (4x + -1x2) + x2(-4 + x)) y = (8 + -2x + 4x + -1x2 + (-4 * x2 + x * x2)) y = (8 + -2x + 4x + -1x2 + (-4x2 + x3)) Combine like terms: -2x + 4x = 2x y = (8 + 2x + -1x2 + -4x2 + x3) Combine like terms: -1x2 + -4x2 = -5x2 y = (8 + 2x + -5x2 + x3) Solving y = 8 + 2x + -5x2 + x3 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Simplifying y = 8 + 2x + -5x2 + x3
