expand (x^2-4)dy+(6x-2xy)dy

expand

(x^{2} - 4) d y + (6 x - 2 x y) d y

x^{2} d y - 4 d y + 6 x d y - 2 x y d y

Solution steps

(x^{2} - 4) d y + (6 x - 2 x y) d y

Expand

d y (x^{2} - 4) : x^{2} d y - 4 d y

= x^{2} d y - 4 d y + (6 x - 2 x y) d y

Expand

d y (6 x - 2 x y) : 6 x d y - 2 x y d y

= x^{2} d y - 4 d y + 6 x d y - 2 x y d y

(1 + x^{2}) y^{3} d x + (1 - y^{2}) x^{3} d y

(3 x^{4} - x^{3} - 2 x^{2} + 3 x - 2) l e f t (x^{3} + 2 x^{2} - 4 x + 1)

(3 a - \frac{1}{4} b)^{2}

\frac{\partial}{\partial y} ((z) (x^{2} + 3 x y + y^{2}))

(a e - b d)^{2} + (a f - c d)^{2} + (b f - ce)^{2}
