if the root of the equation x2-ax+b=0 differ by unity
- a2 is equal to
- 1+a2 is equal to
- if one of the root of the equation x2-ax+b=0 be twice the other then 2a2 is equal to
- if the sum of the root of the equation x2-ax+b=0 is equal to the sum of the square of their reciprocal then a2 is equal to
