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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

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

- 5 \cdot 3

\frac{1}{( 3 x ^{2} + 5 ) ^{4}}

0 (x + 3)^{2} - 2
