Simplifying (x + 3i)(x + -3i) = 9 Reorder the terms: (3i + x)(x + -3i) = 9 Reorder the terms: (3i + x)(-3i + x) = 9 Multiply (3i + x) * (-3i + x) (3i * (-3i + x) + x(-3i + x)) = 9 ((-3i * 3i + x * 3i) + x(-3i + x)) = 9 Reorder the terms: ((3ix + -9i2) + x(-3i + x)) = 9 ((3ix + -9i2) + x(-3i + x)) = 9 (3ix + -9i2 + (-3i * x + x * x)) = 9 (3ix + -9i2 + (-3ix + x2)) = 9 Reorder the terms: (3ix + -3ix + -9i2 + x2) = 9 Combine like terms: 3ix + -3ix = 0 (0 + -9i2 + x2) = 9 (-9i2 + x2) = 9 Solving -9i2 + x2 = 9 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-1x2' to each side of the equation. -9i2 + x2 + -1x2 = 9 + -1x2 Combine like terms: x2 + -1x2 = 0 -9i2 + 0 = 9 + -1x2 -9i2 = 9 + -1x2 Divide each side by '-9'. i2 = -1 + 0.1111111111x2 Simplifying i2 = -1 + 0.1111111111x2 Reorder the terms: 1 + i2 + -0.1111111111x2 = -1 + 0.1111111111x2 + 1 + -0.1111111111x2 Reorder the terms: 1 + i2 + -0.1111111111x2 = -1 + 1 + 0.1111111111x2 + -0.1111111111x2 Combine like terms: -1 + 1 = 0 1 + i2 + -0.1111111111x2 = 0 + 0.1111111111x2 + -0.1111111111x2 1 + i2 + -0.1111111111x2 = 0.1111111111x2 + -0.1111111111x2 Combine like terms: 0.1111111111x2 + -0.1111111111x2 = 0.0000000000 1 + i2 + -0.1111111111x2 = 0.0000000000 The solution to this equation could not be determined.
