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

expand

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

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

Solution steps

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

Expand

2 d x (y + 1) : 2 y d x + 2 d x

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

Expand

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

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

\frac{d}{d t} ((s) (16 t^{2} + 4 t - 1))

- x^{2} - r ((1 - a) y + a x - t)^{2}

y d x + (3 x - x y + 2) d y

\frac{x ^{2} - 5 y}{y ^{2} ( 5 x - 2 y )}

\frac{sin ( 2 ( y - 3 ) )}{2 ( y - 3 )}
