3/2y – 3/2y+4
3/2y - 3/2(y+2) + 4
2y(y+2)[3/2y - 3/2(y+2)+4]
6(y+2) - 6y + 8y(y+2)
6y + 12 - 6y + 8y^2 + 16y
8y^2 + 16y + 12
4/3n + 2/n+1 + 2 n^2+n
3n(n+1)[4/3n + 2/n+1 + 2 n^2+n]
4(n+1) + 3n(2) + 3n(n+1)(2 n^2) +3n(n+1)(n)
4n + 4 + 6n + (3n^2 + 3n)(2n^2) + 3n^2(n+1)
4n + 4 + 6n + 6n^4 + 6n^3 + 3n^3 + 3n^2
6n^4 + 9n^3 + 3n^2 + 10n + 4
