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

expand

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

x d x + 2 y d x + 2 x d y - y d y

Solution steps

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

Expand

d x (x + 2 y) : x d x + 2 y d x

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

Expand

d y (2 x - y) : 2 x d y - y d y

= x d x + 2 y d x + 2 x d y - y d y

\frac{1}{6} (5 - ln (18))

(- 3 a b^{3})^{2}

10 - 20 (e^{- 0.25 x} - e^{- 0.5 x})

(- 3 - - i)^{7}

(3, 7) (x + 4, y - 1)
