Simplifying (x + 3)(x + 2i)(x + -2i) = 0 Reorder the terms: (3 + x)(x + 2i)(x + -2i) = 0 Reorder the terms: (3 + x)(2i + x)(x + -2i) = 0 Reorder the terms: (3 + x)(2i + x)(-2i + x) = 0 Multiply (3 + x) * (2i + x) (3(2i + x) + x(2i + x))(-2i + x) = 0 ((2i * 3 + x * 3) + x(2i + x))(-2i + x) = 0 ((6i + 3x) + x(2i + x))(-2i + x) = 0 (6i + 3x + (2i * x + x * x))(-2i + x) = 0 (6i + 3x + (2ix + x2))(-2i + x) = 0 Reorder the terms: (6i + 2ix + 3x + x2)(-2i + x) = 0 (6i + 2ix + 3x + x2)(-2i + x) = 0 Multiply (6i + 2ix + 3x + x2) * (-2i + x) (6i * (-2i + x) + 2ix * (-2i + x) + 3x * (-2i + x) + x2(-2i + x)) = 0 ((-2i * 6i + x * 6i) + 2ix * (-2i + x) + 3x * (-2i + x) + x2(-2i + x)) = 0 Reorder the terms: ((6ix + -12i2) + 2ix * (-2i + x) + 3x * (-2i + x) + x2(-2i + x)) = 0 ((6ix + -12i2) + 2ix * (-2i + x) + 3x * (-2i + x) + x2(-2i + x)) = 0 (6ix + -12i2 + (-2i * 2ix + x * 2ix) + 3x * (-2i + x) + x2(-2i + x)) = 0 Reorder the terms: (6ix + -12i2 + (2ix2 + -4i2x) + 3x * (-2i + x) + x2(-2i + x)) = 0 (6ix + -12i2 + (2ix2 + -4i2x) + 3x * (-2i + x) + x2(-2i + x)) = 0 (6ix + -12i2 + 2ix2 + -4i2x + (-2i * 3x + x * 3x) + x2(-2i + x)) = 0 (6ix + -12i2 + 2ix2 + -4i2x + (-6ix + 3x2) + x2(-2i + x)) = 0 (6ix + -12i2 + 2ix2 + -4i2x + -6ix + 3x2 + (-2i * x2 + x * x2)) = 0 (6ix + -12i2 + 2ix2 + -4i2x + -6ix + 3x2 + (-2ix2 + x3)) = 0 Reorder the terms: (6ix + -6ix + 2ix2 + -2ix2 + -12i2 + -4i2x + 3x2 + x3) = 0 Combine like terms: 6ix + -6ix = 0 (0 + 2ix2 + -2ix2 + -12i2 + -4i2x + 3x2 + x3) = 0 (2ix2 + -2ix2 + -12i2 + -4i2x + 3x2 + x3) = 0 Combine like terms: 2ix2 + -2ix2 = 0 (0 + -12i2 + -4i2x + 3x2 + x3) = 0 (-12i2 + -4i2x + 3x2 + x3) = 0 Solving -12i2 + -4i2x + 3x2 + x3 = 0 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-3x2' to each side of the equation. -12i2 + -4i2x + 3x2 + -3x2 + x3 = 0 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -12i2 + -4i2x + 0 + x3 = 0 + -3x2 -12i2 + -4i2x + x3 = 0 + -3x2 Remove the zero: -12i2 + -4i2x + x3 = -3x2 Add '-1x3' to each side of the equation. -12i2 + -4i2x + x3 + -1x3 = -3x2 + -1x3 Combine like terms: x3 + -1x3 = 0 -12i2 + -4i2x + 0 = -3x2 + -1x3 -12i2 + -4i2x = -3x2 + -1x3 Reorder the terms: -12i2 + -4i2x + 3x2 + x3 = -3x2 + 3x2 + -1x3 + x3 Combine like terms: -3x2 + 3x2 = 0 -12i2 + -4i2x + 3x2 + x3 = 0 + -1x3 + x3 -12i2 + -4i2x + 3x2 + x3 = -1x3 + x3 Combine like terms: -1x3 + x3 = 0 -12i2 + -4i2x + 3x2 + x3 = 0 The solution to this equation could not be determined.
