I really need help factoring these special Trinomials.

This question really puzzled me. I thought I had it correct, but when I checked the answer at the back of the book, I was wrong, and so I would like to know what was it that I had done wrong.

This was the question:

x^2-4x+4

This is how I solved it:

x^2-4x+4

x^2-2x-2x+4

x(x-2)-2(x+2)

(x-2)(x+2)

- I could not get any further than this. I thought that this would be correct, but the actual answer is

(x-2)^2

How did they get that?

If there is an easier way to solve this, then can you please show me how. Cause solving things like I have above is difficult.
