I've been reviewing all day for a test tommorow and the following are the problems I have no idea how to complete. I don't expect them all to be answered but any help/explanation would be greatly appreciated.

1) Simplify the expression.

$\displaystyle \frac{3(1+x)^1/^3-x(1+x)^-2/^3}{(1+x)^2/^3}$

^Sorry about the messed up exponents.

2) Find all real solutions to the equation.

$\displaystyle \frac{x+5}{x-2}=\frac{5}{x+2}+\frac{28}{x^2-4}$

Thanks.
