Simplifying (4 + -1i)(-21 + 3i) = 0 Multiply (4 + -1i) * (-21 + 3i) (4(-21 + 3i) + -1i * (-21 + 3i)) = 0 ((-21 * 4 + 3i * 4) + -1i * (-21 + 3i)) = 0 ((-84 + 12i) + -1i * (-21 + 3i)) = 0 (-84 + 12i + (-21 * -1i + 3i * -1i)) = 0 (-84 + 12i + (21i + -3i2)) = 0 Combine like terms: 12i + 21i = 33i (-84 + 33i + -3i2) = 0 Solving -84 + 33i + -3i2 = 0 Solving for variable 'i'. Factor out the Greatest Common Factor (GCF), '3'. 3(-28 + 11i + -1i2) = 0 Factor a trinomial. 3((-7 + i)(4 + -1i)) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-7 + i)' equal to zero and attempt to solve: Simplifying -7 + i = 0 Solving -7 + i = 0 Move all terms containing i to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + i = 0 + 7 Combine like terms: -7 + 7 = 0 0 + i = 0 + 7 i = 0 + 7 Combine like terms: 0 + 7 = 7 i = 7 Simplifying i = 7Subproblem 2
Set the factor '(4 + -1i)' equal to zero and attempt to solve: Simplifying 4 + -1i = 0 Solving 4 + -1i = 0 Move all terms containing i to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1i = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1i = 0 + -4 -1i = 0 + -4 Combine like terms: 0 + -4 = -4 -1i = -4 Divide each side by '-1'. i = 4 Simplifying i = 4Solution
i = {7, 4}
