$\displaystyle

f(x)=(x+2)^{2}H(x-3)

$

After looking at some other examples on the forum, I have tried letting $\displaystyle g(t)=(t+5) $ in order to make the two expressions inside the brackets the same, ie $\displaystyle (x-3) $ so that standard rules can be applied, though I am not quite sure if this is right or where to go from here. ANy help would be much appreciated!

Thanks in advance.
