Simplifying -1i(4 + -8i) = 0 (4 * -1i + -8i * -1i) = 0 (-4i + 8i2) = 0 Solving -4i + 8i2 = 0 Solving for variable 'i'. Factor out the Greatest Common Factor (GCF), '4i'. 4i(-1 + 2i) = 0 Ignore the factor 4.Subproblem 1
Set the factor 'i' equal to zero and attempt to solve: Simplifying i = 0 Solving i = 0 Move all terms containing i to the left, all other terms to the right. Simplifying i = 0Subproblem 2
Set the factor '(-1 + 2i)' equal to zero and attempt to solve: Simplifying -1 + 2i = 0 Solving -1 + 2i = 0 Move all terms containing i to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + 2i = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 2i = 0 + 1 2i = 0 + 1 Combine like terms: 0 + 1 = 1 2i = 1 Divide each side by '2'. i = 0.5 Simplifying i = 0.5Solution
i = {0, 0.5}
