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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

(3 x - 1)^{3} ln (- 4 yz) - (7 x^{3} y^{2})

x sin (2) (- 4 ln 4 - x^{2} - x)

\frac{( ( 4 x + x ^{2} ) x )}{( 4 + x ^{2} )}

ln (\frac{x - 67}{x})

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