Simplifying (-9 + -3i)(2 + i) = 0 Multiply (-9 + -3i) * (2 + i) (-9(2 + i) + -3i * (2 + i)) = 0 ((2 * -9 + i * -9) + -3i * (2 + i)) = 0 ((-18 + -9i) + -3i * (2 + i)) = 0 (-18 + -9i + (2 * -3i + i * -3i)) = 0 (-18 + -9i + (-6i + -3i2)) = 0 Combine like terms: -9i + -6i = -15i (-18 + -15i + -3i2) = 0 Solving -18 + -15i + -3i2 = 0 Solving for variable 'i'. Factor out the Greatest Common Factor (GCF), '-3'. -3(6 + 5i + i2) = 0 Factor a trinomial. -3((3 + i)(2 + i)) = 0 Ignore the factor -3.Subproblem 1
Set the factor '(3 + i)' equal to zero and attempt to solve: Simplifying 3 + i = 0 Solving 3 + i = 0 Move all terms containing i to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + i = 0 + -3 Combine like terms: 3 + -3 = 0 0 + i = 0 + -3 i = 0 + -3 Combine like terms: 0 + -3 = -3 i = -3 Simplifying i = -3Subproblem 2
Set the factor '(2 + i)' equal to zero and attempt to solve: Simplifying 2 + i = 0 Solving 2 + i = 0 Move all terms containing i to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + i = 0 + -2 Combine like terms: 2 + -2 = 0 0 + i = 0 + -2 i = 0 + -2 Combine like terms: 0 + -2 = -2 i = -2 Simplifying i = -2Solution
i = {-3, -2}
