I have an Algebra 2 class. At the very last class on Friday (which I could not attend) my professer went over Limits. I do not know exactly what that means, or how to evalueate the limits problems he gave us to work.

Here are some examples
Instruction: Evaluate these problems

Lim x (arrow) 1 ((square root of x+1)-(sqaure root of 2x)/(x squared - x))

Lim x (arrow) infinity ((4x squared+2x+3)/(2x squared - x - 8))

Lim x (arrow) 0 ((x cubed - 5x squared + 4x)/(x squared - x))

I assume that where factoring is part of finding the solution, but I really do not understand how to go about evaluating these problems. This is not something there is anything in the book about, and the teacher is hard to reach being an adjunct, I do know there will be something on the final about these.

Thanks!
