Question

def

Answer 1

\[\begin{align*}
0&=dz-(4x^3-4x^3z+x^3z^2)\,dx+(4y-1)(2-z)^2\,dy\\\\
&=dz-x^3(4-4z+z^2)\,dx+(4y-1)(2-z)^2\,dy\\\\
&=dz-x^3(2-z)^2\,dx+(4y-1)(2-z)^2\,dy\\\\
\frac{dz}{(2-z)^2}&=x^3\,dx+(1-4y)\,dy
\end{align*}\]

Answer 2

Yes yes! You're too fast. Ill just integrate your final answer separately and thats it! Thank you so much @SithsAndGiggles =)
