expand (x^3+2x^2y+9xy+18y)dy

expand

(x^{3} + 2 x^{2} y + 9 x y + 18 y) d y

x^{3} d y + 2 x^{2} y d y + 9 x y d y + 18 y d y

Solution steps

(x^{3} + 2 x^{2} y + 9 x y + 18 y) d y

Distribute parentheses

= d y x^{3} + d y \cdot 2 x^{2} y + d y \cdot 9 x y + d y \cdot 18 y

= x^{3} d y + 2 x^{2} y d y + 9 x y d y + 18 y d y

\frac{7 x ^{2}}{( x + 3 ) ( x + 5 ) ( x - 5 )}

(x + 7)^{(x + 7) 2}

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

\frac{( 5 )}{( ( 3 u ^{2} + 1 ) ^{2} )}

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