Factoring question.

They all have x (and only x), so you could just factor anything out. But yes, normally, you wouldn't want to deal with negative and/or factional exponents, so try to put it out in front whenever you can, and choose the most complicated one among them.



When you get used to analyzing stuff at a glance, you'll see that ^(1/2) is one exponent higher than ^(-1/2) which is in turn 1 exponent higher than ^(-3/2), suggesting the form (ax^2 + bx + c).
