expand xydx+2(x^2+2y^2)dy

expand

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

x y d x + 2 x^{2} d y + 4 y^{2} d y

Solution steps

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

Expand

2 d y (x^{2} + 2 y^{2}) : 2 x^{2} d y + 4 y^{2} d y

= x y d x + 2 x^{2} d y + 4 y^{2} d y

\frac{( - 7 x + 3 ) ( 9 x + 4 )}{24}

(3 + 2) (1 + 3)

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

(5 + 23)^{2} - 10 (5 + 23) + 13

p^{(n - m - 1)^{2}}
