Three zeroes of a fifth degree polynomial function are $\frac{1}{3},4-6i,\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}-2+11i$. determine the remaining zeroes of the function

Nola Robson

Complex zeroes are always in conjugate pairs: so $4-6i$ is paired with $4+6i$, and $-2+11i$ is paired with $-2-11i$.
