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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

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

(- x)^{3}

(3 c e^{3 x} - 5 d e^{- 5 x})^{2}

(a + b + c + d + 1)^{3}

\frac{3 x ^{2} - 4 x - 3}{( 3 x - 2 ) ^{2}}
