I do know how to tackle the question with that rule but I am unsure as to what the actual answer would come out looking like due to the square root.
Well what have you tried? Don't shy away just because it looks a little more difficult than normal. You'll never achieve anything like that...
Show us what you've got. If it isn't right, we'll help.
No as in I have written it out three times and then tried it on the calculator and all three times it has been wrong. So far I have gotten 34.963569(x-60) +82.782(sq root) x-60 +49
Assuming that sqrt is supposed to cover (x - 60) [some brackets where they're needed would be nice] I agree with your answer...
If I were to integrate that, how would i actually do it with the square root there? Would I also be able to expand the first part of the equation to 34.963569x-2097.81414? How could i expand the second part like that to make it easier to integrate?
Try a u-substitution with u = x - 60.
