inverse of (2+x-x^2)/((x-1)^2)

inverse

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

\frac{2 x + 1 + 8 x + 9}{2 ( x + 1 )}, \frac{2 x + 1 - 8 x + 9}{2 ( x + 1 )}

Solution steps

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

Replace

x

with

y

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

Solve for

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

\frac{2 x + 1 + 8 x + 9}{2 ( x + 1 )}, \frac{2 x + 1 - 8 x + 9}{2 ( x + 1 )}
