What is the derivative of your substitution? Does it appear in your original Integral?

Try re-writing your Integral as $$\int6x^{-2}dx$$ do you see what to do next?

Oh ofcourse - you would then say add one to the power and divide by the new power which becomes -6/x

thanks - (i must have had a mental block :) )
