expand (3x^2-y)dx+(3y^2-x)dy

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

4 (x \frac{d y}{d x} + y)

(3, - 1) x (- 1, 3)

\frac{( 7 - s )}{( ( s - 1 ) ( s - 4 ) )}

- \frac{32}{( 2 x + 1 ) ^{3}}

\frac{x + 3}{( x ^{2} + 9 ) ^{2}}
