Question from Russell, a student:

integrate (4+x^2) / (x (2+x)^2)
I really need to know the steps involved in doing this integral, I already have the answer through wolfram intefrator but for some reason can not get to the answer given. Please help

Hi Russell,

Write 4 + x2 as x2 + 4x + 4 - 4x = (x + 2)2 - 4x

Does that help?
