Can someone please point out where I went wrong?
First, I complete the square:
Factor out a 16:
Let U = & dU=1\4dx :: dx=4du
It seems like my answer is wrong however. Where did I go wrong?
^ Thank you!
I fixed that problem. Are you using trig substitution to solve this? I havnt learned that very well yet.
Couldnt I still get this into the same form as arccos using the same method I attempted, but this time with an answer of:
arccos((x-2)/4) + C
