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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

s im pl f y (- 5 y + \cdot 7) (85 - x) 48

10 (x - y = 7)

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

- 4 (m x - m + 4)^{2}

\frac{5 x + 1}{( x + 1 ) ( x + 10 ) ( 2 x - 1 )}
