Best ResponseYou've already chosen the best response.2so far i think it is b but i feel it can be simplified further :)

Best ResponseYou've already chosen the best response.2If you know algrabeic long division then there is a theory of if you divide your given polynomial in this case 2x3  5x2y + xy2 + 2y3 by a suspected binomial or trinomial (2x + y) or (x2 3xy + 2y 2 ) ^ those are from B the 2 expressions inside the ( ) and you get 0 then that trinomial or binomial is a factor and therfore part of the answer :)

Best ResponseYou've already chosen the best response.2if you get a remainder of 0 :P

Best ResponseYou've already chosen the best response.2in other words 2x3  5x2y + xy2 + 2y3  = (x2 3xy + 2y 2 ) with no remainder (2x + y) and obviously 2x3  5x2y + xy2 + 2y3  = 2x+y with no remainder (x2 3xy + 2y 2 )

Best ResponseYou've already chosen the best response.2But if you dont know algabreic long division dont bother with that method :P
