Hi guys. Looking at the integral, I initially thought using partial fractions would make it a piece of cake, but obviously x^2+2x+4 cannot be factored. So, I completed the square, giving us int of (x+4)/[(x+1)^2+3]. This looks as if we should use trig sub... could someone please show me their method to integrate this function? I'm 99% sure I solved it COMPETELY wrong. Please help! Thank you =D

X- ___2___
x^2-9
___________
__1___
x-3

This is a double fraction question, i'm sorry but i did my best with what is available on my keyboard. The top half of the fraction is X minus (another fraction) 2 over x to the second power minus nine. this is all over the bottom half of the larger fraction which is 1 over x-3. Help!

P.S. I know that simplying the bottom half of the top equation x to the 2nd power minus 9 would make (x-3)(x+3) would give a common demoniator. I am unsure of actions after that.
