Homework Statement
this is LFS of a question,which is
(1+x)/(1-x-x^2) dx!
i can not simplefy it at all b4 try to do d integration!

SUMMARY
The discussion focuses on simplifying the integral of (1+x)/(1-x-x^2) dx by completing the square for the quadratic expression in the denominator. The integral can be rewritten as the sum of two simpler integrals by expressing (1+x)/(1-x-x^2) in the form (a+b)/c. This method allows for easier integration and clearer analysis of the function's behavior.
