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

expand

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

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

Solution steps

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

Expand

x^{2} d x (x + 1) : x^{3} d x + x^{2} d x

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

Expand

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

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

0.275 x + 0.725 (450 - x = 295)

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

(\frac{2}{3}, \frac{10}{3}) y (- \frac{8}{3}, - \frac{10}{3})

\frac{( n + 1 ) n ( n - 1 )}{6}

\frac{4 s}{( L ( 4 s ^{2} + 1 ) )}
