# Math Help - First-order differential/seperable equation problem

1. ## First-order differential/seperable equation problem

How do I solve the following?: du/dt = 2 + 2u + t + tu

What I tried:
I multiplied both sides by dt but then I know I have to isolate u but how do I do that?

Any help would be greatly appreciated!
2. $2+2u+t+ut=2(u+1)+t(u+1)=(u+1)(2+t),$ so your equation is separable.
