Divide the magnitudes and subtract the angles.

so that would be sqrt(5) L3.32145... could you take a look at the original problem and tell me if I am right...(1+2j)^2/(1-2j) they wanted the solution in polar.

Looks OK.

thanks i just wasnt sure about the angle, my calculator says it should be 0.1799, probably co-terminal or in a different quadrant or something?

Different quadrant - third quadrant. If you used arctan, you'll get an angle in the first or fourth quadrant.
