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

expand

(2 x - y) d x + (x + 3 y) d y

2 x d x - y d x + x d y + 3 y d y

Solution steps

(2 x - y) d x + (x + 3 y) d y

Expand

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

= 2 x d x - y d x + (x + 3 y) d y

Expand

d y (x + 3 y) : x d y + 3 y d y

= 2 x d x - y d x + x d y + 3 y d y

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

x (\frac{x}{2} - 8 = y)

\frac{( 3 x - 9 ) ^{2}}{16}

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

6 \cdot 2
