expand (y^2-1)dx+(2xy)dy

expand

(y^{2} - 1) d x + (2 x y) d y

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

Solution steps

(y^{2} - 1) d x + (2 x y) d y

= (y^{2} - 1) d x + (2 y x) d y

Expand

d x (y^{2} - 1) : y^{2} d x - d x

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

Remove parentheses:

(a) = a

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

(6 + e^{x})^{2}

g (3 = 3 (- 1)^{2} - 2 (- 3) + 2)

\frac{d}{d t} ((x) (k x (t) (1000 - x)))

\frac{5 x - 2}{( x - 2 ) ( x + 2 )}

\frac{2}{y ( y + 8 )}
