expand-(2x)/((x+y)^3)

expand

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

- \frac{2 x}{x ^{3} + 3 x ^{2} y + 3 x y ^{2} + y ^{3}}

Solution steps

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

(x + y)^{3} = x^{3} + 3 x^{2} y + 3 x y^{2} + y^{3}

= - \frac{2 x}{x ^{3} + 3 x ^{2} y + 3 x y ^{2} + y ^{3}}

(\frac{x + y - 4 β}{4}) (0, - 6, - 6)

3 (2 n + 4) + 5 (3 - 2 n = 7 - 2 n)

\frac{a}{( a - 1 ) ^{2}}
