1. The problem statement, all variables and given/known data
I know the integral of 6/(x^2) is 6/x but what are the steps to achieve this...

2. Relevant equations

3. The attempt at a solution

Does it involve the substitution u=(x^2) then what is the next step......

thanks

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 :) )
