The given equation

and we have to find m= ______ ± ________
We can use quadratic formula to solve this question.
The above equation can be written as: 
and the formula used will be:

Putting values of a= 1, b= -5/2 and c= 11/2 and solving we get:
Since there is - sign inside the √ so
is equal to i and we have to divide
into its multiples such that the square root of one multiple is whole no so,
=
=
Putting value of
and 
the value of m= 
so, correct option for first blank is 5/4 and for second blank is
.
