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

expand

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

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

Solution steps

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

(x - 1 - x + 1)^{2}

2 (e^{2} - e)

(7 x^{3} + 4 x^{2}) d x

\frac{k ^{2} ( k + 1 ) ^{2}}{4} + (k + 1)^{3}

\frac{2}{s ^{2} ( s + 2 )}
