Simplify: Simplification Involving Radicals

[Guest]

Got another tricky one that I can't figure out

((x^3) - x + 1) / Sqrrt(x)

Any help with this is greatly appreciated.

To rationalize the denominator, multiply the fraction by "sqrt[x] / sqrt[x]".

No, this won't be "simpler" than what you started with, but that's almost certainly what they mean by "simplify". :shock:

Is this the only real way to simplify it? I figured that it would involve something along the lines of that but I didn't know if that was the only thing that could be done...

Your final answer can't have a square root in the denominator, that is just a common rule in math. If you leave the sqrt in the denominator, then your answer is wrong.

It's a common rule in high-school algebra, anyway. Once you get to calculus, it's entirely possible that nobody will care anymore.
