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

expand

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

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

Solution steps

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

Expand

d x (x^{2} + y^{2}) : x^{2} d x + y^{2} d x

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

Expand

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

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