Simple anti-derivative problems. I missed the lecture on this and need to be walked through this: Indefinite integral for: (4t-9)^-3 and (x^2+2x-3)/(x^4) thanks a lot

That's just it; I can't see the answer. Originally Posted by Mathstud28 you have ...now we can rewrite this as ....and now using the rules of we can see the answer easily and you also have ...split the fraction apart to get and the answer should be readily apparent

How do you get there though? Originally Posted by Mathstud28 the first answer is ...the second answer is

Let . So: So performing your substitution: And this should be a standard one. For the second one, what MathStud was saying was to split the fraction up: See how each term cancels into something you can integrate rather easily?

What do you mean? I just replaced 4t + 9 with u. The exponent -3 remains the same.
