Solve (1)/(x-2)+(1)/(x-1) gt (1)/(x)....

Solve `(1)/(x-2)+(1)/(x-1) gt (1)/(x)`.

Text Solution

Verified by Experts

The correct Answer is:
`x in (-sqrt(2),0) uu (1,sqrt(2)) uu (2,oo)`
`(1)/(x-2)+(1)/(x-1) gt (1)/(x)`
`implies (2x^(2)-3x-x^(2)+3x-2)/((x-2)(x-1)x)gt0`
`implies (x^(2)-2)/((x-2)(x-1)x) gt 0`

`x in (-sqrt(2),0)uu(1,sqrt(2))uu(2,oo)`
