expand (x-2y)dx+2(y-x)y

expand

(x - 2 y) d x + 2 (y - x) y

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

Solution steps

(x - 2 y) d x + 2 (y - x) y

= (x - 2 y) d x + 2 y (y - x)

Expand

d x (x - 2 y) : x d x - 2 y d x

= x d x - 2 y d x + 2 (y - x) y

Expand

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

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

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

(4 x - 2)^{2} es

\frac{r}{( r - 9 ) ^{4}}

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

x y d x - (x + 2) d y
