Just use an example you know is true: \[\frac{ 4 }{ 8 } x = \frac{ 1 }{ 2 } x \] Multiply both sides by two and you get x=x

You could forget the x part is you think of x=1, but it will work for any x.

Wouldn't it have to be something like (x^2 +5)/(x+2)?

No... rational means it can be expressed as a fraction with integers on top and bottom

Both a ratio of polynomials and of integers are a "rational expression", and, in any case, you can use the same example to prove it for polynomials as well.

What about ((x^2)+10)/(x+5)=x+2?

x+2 is the reduced form, but it doesn't turn out to x=x does it?
