Answer:5/2

Step-by-step explanation:let the roots of the quadratic queation be a and b

a+b=21/8

ab=5/16

(a-b)^(2)=(a+b)^(2)-4ab

              =21^(2)/8^(2)-4*5/16

               =441/64-20/16  

                =(441-80)/64

                =361/64

(a-b)^(2)=(19)^(2)/8^(2)

a-b=19/8----(1)

a+b=21/8------(2)

solving eq(1) and (2)..

a=5/2, b=1/8
