How to integrate a quadratic as the denominator.

Click For Summary
SUMMARY

The integration of the function \(\int\frac{1}{F-Gx+x^{2}}dx\) can be solved using the method of completing the square and substitution. The discussion highlights that the result is related to the inverse hyperbolic tangent function. Specifically, the process involves transforming the quadratic expression \(x^2 - Gx + F\) into a completed square form, which simplifies the integration process. The steps for completing the square are clearly outlined, providing a systematic approach to tackle similar integrals.

Homework Statement


I'm having major issues working out how to integrate
[tex]\int\frac{1}{F-Gx+x^{2}}dx[/tex] , where F and G are constants.





Homework Equations





The Attempt at a Solution



Maple tells me it is an inverse hyperbolic tangent of some description, and I know I have to complete the square and use substitution, but I really don't understand how! Any pointers would be great.
Is there a general formula for this sort of thing?
Thanks.

If you complete the square of x^2-Gx+F what do you get?
 
To be precise, to complete the square follow these steps -:
1. Take the coefficient of the x term, half it.
2. Square this halved coefficient and then add and subtract it to the expression.
3. Complete the square.

Surely you can finish this now.
