expand xydx+(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 d y

Solution steps

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

Expand

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

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

\frac{( 2 + x ) ^{2}}{25}

\frac{d ^{2}}{d x ^{2}} ((y) x (x - 2))

\frac{s + 1}{s ( s ^{2} + 2 s + 2 )}

\frac{( x - 6 ) ( x + 1 )}{( x - 3 ) ( x + 2 )}

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