Answer
$1\pm i$
Work Step by Step
Step 1. From the given graphs, we can find two real zeros $x=2,3$
Step 2. Use the given coefficients from the polynomial, perform synthetic divisions as shown in the figure.
Step 3. Use the quotient to get the remaining zeros. $x^2-2x+2=0$, thus $x=\frac{2\pm\sqrt {2^2-4(2)}}{2}=1\pm i$
