  1. You forgot to multiply sqrt(x) with -3sqrt(x) and add this to the result.

    If you do so, you get an additional term with -3x

    How do you find a square root of a number that's not a perfect square? I'm very confused. The book doesn't explain it too well. You can approximate it or simplify it in terms of (products of) square roots of smaller numbers. E.g.
