(integral of) 2y^4dy/y^3 - y^2 + y - 1

After long divison I get:

(integral of)2ydy + 2(integral of)dy + (integral of) 2/y^3 - y^2 + y - 1

I keep getting stuck here. I can't write this as a sum of partial fractions because I can't figure out how to rearrange the denominator so that I CAN write it as a sum o partial fractions. Any ideas?

y^3 - y^2 + y - 1

= y^2(y-1) + (y-1)

= (y-1)(y^2 + 1)
