expand (xy)dx+(2x^2+3y^2=20)dy

expand

(x y) d x + (2 x^{2} + 3 y^{2} = 20) d y

x y d x + 2 x^{2} d y + 3 y^{2} d y = 20

Solution steps

(x y) d x + (2 x^{2} + 3 y^{2} = 20) d y

= (x y) d x + (2 x^{2} + 3 \cdot 20 = y^{2}) d y

Expand

d y (2 x^{2} + 3 y^{2} = 20) : 2 x^{2} d y + 3 y^{2} d y = 20

(x y) d x + 2 x^{2} d y + 3 y^{2} d y = 20

Expand

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

x y d x + 2 x^{2} d y + 3 y^{2} d y = 20

A (4 - 2) C (2, - 8)

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

(2 x - e^{x}) \cdot (e^{- x} + 1)

\frac{45 a}{( x + 2.9 ) ( x + 0.14 )}

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