Integral of [ (2x+3) / (x^2 +2x + 5)^2 ] dx
How do I begin? Partial fractions?
Nope, partial fractions won't work here. I'm running on too little sleep to figure out why. But trig. substitution will work!
Note that your integral is:
So let and your integral becomes:
which is very doable. The rest is left to you. Don't forget to back-substitute when done
