expand ((xy+1)^2)/(xy-1)

expand

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

\frac{x ^{2} y ^{2} + 2 x y + 1}{x y - 1}

Solution steps

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

(x y + 1)^{2} = x^{2} y^{2} + 2 x y + 1

= \frac{x ^{2} y ^{2} + 2 x y + 1}{x y - 1}

(8 hk + 5 e f) (8 hk - 5 e f)

(\frac{x + 1}{2})^{5}

\frac{6 ( 1 - cos ( x ) )}{x ^{2}}

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

t^{3} (e^{- a t} + 1)^{2}
