expand (x+y-2)dx+(x-y+4)dy

expand

(x + y - 2) d x + (x - y + 4) d y

x d x + y d x - 2 d x + x d y - y d y + 4 d y

Solution steps

(x + y - 2) d x + (x - y + 4) d y

Expand

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

= x d x + y d x - 2 d x + (x - y + 4) d y

Expand

d y (x - y + 4) : x d y - y d y + 4 d y

= x d x + y d x - 2 d x + x d y - y d y + 4 d y

\frac{d}{d x} ((x - 1) (x - 5)^{3}) + 1

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

(x + 2 + 3) (x + 2 - 3)

t u (t - 5)

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