NOTE: square root of 1 is 1 and sq root of 1+a is always >1 (where a can be an integer or fraction) .
As u can see i have ignored the - ve sign while solving the quadratic as if took the - ve sign then my answer would be option 3 which is incorrect as root over 1 + 2gh/ v^2 is >1 and if we subtract this from 1 we get -ve value of time
