Solve the problem.
-$3 + 6 i$ is a zero of a quadratic function with real coefficients. Find the other zero.
A) $3 - 6 i$
B) $6 \mathrm { i } - 3$
C) $- 3 - 6 i$
D) 9

Question

Quizplus · Accepted Answer

If a quadratic function has real coefficients and one complex zero, the other zero must be the complex conjugate of the first. Since $3 + 6i$ is a zero, the other zero is its complex conjugate, $3 - 6i$.
