Best ResponseYou've already chosen the best response.2Just 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

Best ResponseYou've already chosen the best response.0No... rational means it can be expressed as a fraction with integers on top and bottom

Best ResponseYou've already chosen the best response.2Both 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.

Best ResponseYou've already chosen the best response.0x+2 is the reduced form, but it doesn't turn out to x=x does it?
