expand (y^2+3)dx+(2xy-4)dy

expand

(y^{2} + 3) d x + (2 x y - 4) d y

y^{2} d x + 3 d x + 2 y x d y - 4 d y

Solution steps

(y^{2} + 3) d x + (2 x y - 4) d y

= (y^{2} + 3) d x + (2 y x - 4) d y

Expand

d x (y^{2} + 3) : y^{2} d x + 3 d x

= y^{2} d x + 3 d x + (2 x y - 4) d y

Expand

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

= y^{2} d x + 3 d x + 2 y x d y - 4 d y

\frac{x - 2}{2 x}

\frac{( x ^{3} + 1 ) ^{3}}{9}

0.5 \cdot (x^{2} - 4 Lx + 4 L^{2})^{2}

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

(16900 - 260 a + a^{2}) + 360 a - 21600
