Answer
$3+2i,-2,5$
Work Step by Step
Step 1. Given a zero $x=3-2i$, we know another zero is $x=3+2i$, thus $(x-3+2i)(x-3-2i)=x^2-6x+13$ is a factor.
Step 2. Perform a division as shown in the figure to get the quotient $x^2-3x-10$ (one can also perform synthetic divisions to get the same result).
Step 3. Solve $x^2-3x-10=0$ or $(x+2)(x-5)=0$ to get $x=-2,5$
