Hello, First time poster here. After lurking about the forums for a couple days I feel as if this question may be overly rudimentary; regardless, I'm stuck. This is not a homework assignment but preparation for an upcoming precalculus class. (x^2-4)((x^2+3)^1/2) - ((x^2-4)^2) ((x^2+3)^3/2) - Factor and simplify I understand that (x^2-4) by itself can be broken down to (x-2)(x+2). However I don't think that is getting me anywhere. Beyond that, I know that obviously (x^2-4) is a factor of ((x^2-4)^2) as well as ((x^2+3)^1/2) being a factor of ((x^2+3)^3/2). With that said, I would rearrange to (x^2-4)(1+(x^2-4)) and ((x^2+3)^1/2)(1+(x^2-4)). Outside of that, I am lost. I realize that I'm seemingly ignoring that subtraction sign there, but in all honesty, I just don't know how to make it fit. Any help would be appreciated.
