Simplifying f(x) = (x + 1)((x + -4) + -5i) Multiply f * x fx = (x + 1)((x + -4) + -5i) Reorder the terms: fx = (1 + x)((x + -4) + -5i) Reorder the terms: fx = (1 + x)((-4 + x) + -5i) Remove parenthesis around (-4 + x) fx = (1 + x)(-4 + x + -5i) Reorder the terms: fx = (1 + x)(-4 + -5i + x) Multiply (1 + x) * (-4 + -5i + x) fx = (1(-4 + -5i + x) + x(-4 + -5i + x)) fx = ((-4 * 1 + -5i * 1 + x * 1) + x(-4 + -5i + x)) fx = ((-4 + -5i + 1x) + x(-4 + -5i + x)) fx = (-4 + -5i + 1x + (-4 * x + -5i * x + x * x)) Reorder the terms: fx = (-4 + -5i + 1x + (-5ix + -4x + x2)) fx = (-4 + -5i + 1x + (-5ix + -4x + x2)) Reorder the terms: fx = (-4 + -5i + -5ix + 1x + -4x + x2) Combine like terms: 1x + -4x = -3x fx = (-4 + -5i + -5ix + -3x + x2) Solving fx = -4 + -5i + -5ix + -3x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = -4x-1 + -5ix-1 + -5i + -3 + x Simplifying f = -4x-1 + -5ix-1 + -5i + -3 + x Reorder the terms: f = -3 + -5i + -5ix-1 + -4x-1 + x
