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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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