expand (2x-2y)dx+(y-1)dy

expand

(2 x - 2 y) d x + (y - 1) d y

2 x d x - 2 y d x + y d y - d y

Solution steps

(2 x - 2 y) d x + (y - 1) d y

Expand

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

= 2 x d x - 2 y d x + (y - 1) d y

Expand

d y (y - 1) : y d y - d y

= 2 x d x - 2 y d x + y d y - d y

\frac{2}{( s - 3 ) ( s ^{2} + 4 )}

\frac{\frac{d}{d x} ( x ^{2} - 2 x )}{( x - 1 ) ^{2}}

(- 3 cos (2 x) - sin (3 x) - 5)^{2}

(x + 2) (x + \frac{3}{5})

(x - 2) (x^{2} + 2 x + 4)^{'}
