How do you do synthetic division to find

(x^2 + 4) Divided By (x-2i)

and

f(x)= x^3 -3x^2 +x -3

zero at x = 3

I learn by examples, so please show work!

If you don't want to tell me the answer, just give a example similar to the problems above and the answer and steps to solve the example problem.

Thank You Very Very much!
