Doing some simple antiderivatives and I wanted to rationalize the denominator of one of the questions to eventually expand the expression:
QUESTION: (2 + x^2)/(1 + x^2), find the antiderivative
*So i mulitiplied the expression by (1-x^2)/(1-x^2) which is technically = to 1
*I ended up with 1 - x^4 in the denominator still and it seems i'm unable to cancel this, I was meaning to end up with my expression all over 1
Am I rationalizing the denominator correctly? Or in this particular question are u unable to rationalize the denominator?
Thanks!
