Ans. \(({x \over (x+1)})^2 - 5 ({x \over (x+1)}) + 6 = 0\)

\(Put \space ({x \over (x+1)}) = y, We \space get \)

=> \(y^2 -5y +6 =0\)

=> \(y^2 - 3y -2y +6 = 0\)

=> \(y(y-3) -2(y-3) = 0\)

=> \((y-3)(y-2) = 0\)

=> y = 3 , 2

Now, \({x\over (x+1) } = 3 \space \space or \space \space {x\over (x+1) } = 2\)

=> x = 3x +3       or     x = 2x + 2

=> x = -3/2         or    x = -2 

Values of x = -3/2, -2
