X = 3 Explanation: Here we go... x + 1 x − 1 = x 3 + 2 x − 1 x + 1 x − 1 = x 2 − x + 6 3 x − 3 ( x + 1 ) ( 3 x − 3 ) = ( x − 1 ) ( x 2 − x + 6 ) 3 x 2 − 3 = x 3 − 2 x 2 + 7 x − 6 x 3 − 5 x 2 + 7 x − 3 = 0 By factorizing this equation we get : ( x − 1 ) ( x − 1 ) ( x − 3 ) = 0 ∴
x = 1 or 3 But as observed in the given question x − 1 is in denominator, So x cannot be equal to 1. Hence, x = 3 Pa brainliest

By factorizing this equation we get :
(
x

)
(
x
−

)
(
x
−

)
= 0
∴
x
=
1
or
3
But as observed in the given question
x
−
1
is in denominator, So
x
cannot be equal to 1.
Hence,
x
