ganeshie8Best ResponseYou've already chosen the best response.1
hmm interesting.. its already in factored form i guess we cant factor it any further

yea this makes sense :)

ganeshie8Best ResponseYou've already chosen the best response.1
just have to multiply..

in between them, would i use ()+()+() or just ()()()?

thats right ! in between we add. () + () + ()

see if above makes sense

ganeshie8Best ResponseYou've already chosen the best response.1
thats almost right !! except for \(24y\)

i mistyped it. lool. its (20xy+32)

and see if any like terms are there

if we ignore that 24y mistype, your final polynomial looks good except for one thing
