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

expand

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

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

Solution steps

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

Expand

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

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

(\frac{8}{x} - \frac{1}{x ^{3}})^{2}

\frac{2}{9} \cdot (3 + \frac{9}{5}) - 1.5 \cdot \frac{4}{5}
