Simplifying (4 + -5i)(4 + i) = 21 + -16i Multiply (4 + -5i) * (4 + i) (4(4 + i) + -5i * (4 + i)) = 21 + -16i ((4 * 4 + i * 4) + -5i * (4 + i)) = 21 + -16i ((16 + 4i) + -5i * (4 + i)) = 21 + -16i (16 + 4i + (4 * -5i + i * -5i)) = 21 + -16i (16 + 4i + (-20i + -5i2)) = 21 + -16i Combine like terms: 4i + -20i = -16i (16 + -16i + -5i2) = 21 + -16i Add '16i' to each side of the equation. 16 + -16i + 16i + -5i2 = 21 + -16i + 16i Combine like terms: -16i + 16i = 0 16 + 0 + -5i2 = 21 + -16i + 16i 16 + -5i2 = 21 + -16i + 16i Combine like terms: -16i + 16i = 0 16 + -5i2 = 21 + 0 16 + -5i2 = 21 Solving 16 + -5i2 = 21 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + -5i2 = 21 + -16 Combine like terms: 16 + -16 = 0 0 + -5i2 = 21 + -16 -5i2 = 21 + -16 Combine like terms: 21 + -16 = 5 -5i2 = 5 Divide each side by '-5'. i2 = -1 Simplifying i2 = -1 Reorder the terms: 1 + i2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + i2 = 0 The solution to this equation could not be determined.
