Best ResponseYou've already chosen the best response.0so we don't FOIL in this case?

Best ResponseYou've already chosen the best response.0just add the common values? the x's and y's?

Best ResponseYou've already chosen the best response.1FOIL method will be too long so you must try to factor the numerator and then cancel the common terms in the numerator nd denominator x^36y^36 = (x^18y^18)(x^18+y^18)

Best ResponseYou've already chosen the best response.0can you do that with the denominator?

Best ResponseYou've already chosen the best response.0but why not? Since they're multiply isnt it dw:1439310745161:dw

Best ResponseYou've already chosen the best response.1the denominator  (x^18+y^18)(x^9+y^9) =x^27 + (x^18)(y^9) + y^27 +(x^9)(y^18)

Best ResponseYou've already chosen the best response.0So you're saying the denominator must be FOILed right?

Best ResponseYou've already chosen the best response.0NOOOOOO i know what youre gonna say you're gonna say it's too long to FOIL but i'm just asking in general you cant add them like i asked previously because in these problems it has to be foiled right?

Best ResponseYou've already chosen the best response.1my method to solve the problem = we can write the numerator as  (x^36y^36) = (x^18+y^18)(x^18y^18) =(x^18+y^18)(x^9+y^9)(x^9y^9) so now we plug this value of numerator in  (x^36y^36)/[(x^18+y^18)(x^9+y^9)] so we have  [(x^18+y^18)(x^9+y^9)(x^9y^9)]/[(x^18+y^18)(x^9+y^9)] after cancelling the common terms we have  x^9y^9 as our answer
