you have everything except the y cubed right.
change that to
y^3(1+3x) + ... and you have it.
arramge terms in each polynomial in ascending powers of y.
y^3+xy^2+y+2-2x^2t+3xy^3+x^3
please help.

oops, you asked for ascending...
(2-2x^2t+x^3)y^0+ y + xy^2 + y^3(1+3x)
(2-2x^2t+x^3)y^0+ y + xy^2 + y^3(1+3x)
