Core 4 A level Integration by Substitution

Use the given substitution to find the following integrals:
2/?x(x-4) u=?x

I know the method, but i just can't seem to apply it
Every time i've done this question i've ended up with something that just won't integrate

Any help would be GREAT
Please show your method ^_^

Is the '?' supposed to be a square root?

What have you tried? Note that if

u=\sqrt{x}

then

x=u^2

, so

dx = 2u\, du

, etc...

After you've done the substitutions, partial fractions may prove to be useful.

OP

Yeah the ? is a square root
I guess it didn't recognise the symbol :/
