expand y(y+2x+1)dx+x(2y+x-1)dy

expand

y (y + 2 x + 1) d x + x (2 y + x - 1) d y

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

Solution steps

y (y + 2 x + 1) d x + x (2 y + x - 1) d y

Expand

y d x (y + 2 x + 1) : y^{2} d x + 2 y x d x + y d x

= y^{2} d x + 2 y x d x + y d x + x (2 y + x - 1) d y

Expand

x d y (2 y + x - 1) : 2 y x d y + x^{2} d y - x d y

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

(x^{3} + 3) δ (x)

(y = - \frac{3}{8} x + 5) (- 8)

(e^{- 2 x} - e^{- 3 x})^{2}

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

x^{6} (2 x - 5 ln (x))
