Thank you :D That really cleared it up! I never had anyone explain that concept so well before.

**Algebra**

I had to solve the function g of f where f is x^2+1 and g is sq. root of x. I wrote this out as the sq. root of x^2+1. The ^2 and the sq. root canceled each other out, so I was left with x + sq. root of 1. But my book got sq. root of x^2+1. Was the further reducing I did ...

I distributed 3x^2+x-10=f(x) to find the zeroes. My book's answer was (3x-5)(x+2). When I distributed this to make sure I got the original function, I got 3x^2-x-10. Is this still an acceptable way to factor it even though the x is negative instead of positive as it should...
