# Math Help - y' + y = 3y^2

1. ## y' + y = 3y^2

what s the solution of y' + y = 3y^2 which graphic contans the pont(1,1).

thank you for ur help

2. ## Re: problem on diferential eq.

$\frac{dy}{dx}=3y^2-y$

$\int\frac{dy}{3y^2-y}=\int dx$

Can you proceed?

i still have problems with that integral..
