Simplifying (-3x + 9i)(x + 3i) = -3x2 + -27 Reorder the terms: (9i + -3x)(x + 3i) = -3x2 + -27 Reorder the terms: (9i + -3x)(3i + x) = -3x2 + -27 Multiply (9i + -3x) * (3i + x) (9i * (3i + x) + -3x * (3i + x)) = -3x2 + -27 ((3i * 9i + x * 9i) + -3x * (3i + x)) = -3x2 + -27 Reorder the terms: ((9ix + 27i2) + -3x * (3i + x)) = -3x2 + -27 ((9ix + 27i2) + -3x * (3i + x)) = -3x2 + -27 (9ix + 27i2 + (3i * -3x + x * -3x)) = -3x2 + -27 (9ix + 27i2 + (-9ix + -3x2)) = -3x2 + -27 Reorder the terms: (9ix + -9ix + 27i2 + -3x2) = -3x2 + -27 Combine like terms: 9ix + -9ix = 0 (0 + 27i2 + -3x2) = -3x2 + -27 (27i2 + -3x2) = -3x2 + -27 Reorder the terms: 27i2 + -3x2 = -27 + -3x2 Add '3x2' to each side of the equation. 27i2 + -3x2 + 3x2 = -27 + -3x2 + 3x2 Combine like terms: -3x2 + 3x2 = 0 27i2 + 0 = -27 + -3x2 + 3x2 27i2 = -27 + -3x2 + 3x2 Combine like terms: -3x2 + 3x2 = 0 27i2 = -27 + 0 27i2 = -27 Solving 27i2 = -27 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Divide each side by '27'. 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.
