Number of integral solutions of (x+2)/(x...

Number of integral solutions of `(x+2)/(x^2 + 1) gt 1/2` is

Text Solution

Verified by Experts

The correct Answer is:
`-1 le x lt 3 `
(x+2)/(x^2+1)gt 1/2
or` (x+2)/(x^2+1)-1/2 gt 0`
or `(3+2x+x^2)/2(x^2+1) gt 0 `
or `(3+2x-x^2)/2(x^2+1)gt 0 `
`or x^2-2x-3lt 0`
`or (x-3)(x+1) lt 0`
`rArr -1 lt x lt 3 `
