expand x^2ydx-2x(x^2+y^2)dy

expand

x^{2} y d x - 2 x (x^{2} + y^{2}) d y

x^{2} y d x - 2 x^{3} d y - 2 x y^{2} d y

Solution steps

x^{2} y d x - 2 x (x^{2} + y^{2}) d y

Expand

- 2 x d y (x^{2} + y^{2}) : - 2 x^{3} d y - 2 x y^{2} d y

= x^{2} y d x - 2 x^{3} d y - 2 x y^{2} d y

\frac{m}{( m x + n ) ( - m x + n )}

\frac{( 2 + y ) ^{2}}{4}

(3 - 3 i)^{7}

\frac{1}{( x ^{2} + 4 ) ( x + 2 )}

3 (\frac{3 π}{2} - \frac{9 3}{4})
