i have looked ALL over the place and found many articles about the Fundamental Theorem of Algebra, yet none of them seem to make any sense to me. I am only in Algebra 1 and the discriptions of the theory are too hard for me to understand. I would really appreciate if someone could explain it on MY level or give me a link to an article that explains it in an EASY WAY!! PLEASE HELP ME!!

ok, the question is to find the limit as x approaches infinity of (x^3 - 5x^2 + x + 2)^(1/3) - x

I know that as x goest to infinity the small powers of x and the constants become insignificant, and the problem becomes
(x^3 - 5x^2)^(1/3) - x = or x(1 - 5/x)^(1/3) - x

but I don't see how you go from

x(1-5/x)^(1/3) - n
to:
x(1 - 5/(3x) + O(1/x^2)) - x

can someone explain this step in detail, thank you

a massless rope is strung over a frictionless pulley. A monkey holds onto the rope, and a mirror having the same wieght as the monkey, is attached on the other side of the rope at the monkeys level.
(a) climbing up the rope
(b) climbing down the rope
(c) releasing the rope

explain...
for all the answers i put no. because the weight is the same, so there is same amount of tension and accleration...but the accleration is just in same magnitude but opposite direction. am i right? rather, is the explanation i provided right?
