If `(3 + i )` is a root of the equation `x^2+ax+b=0` then `a` is

The roots of the equation x^2+ax+b=0 are

If 1 - I is a root of the equation x^(2) + ax +b = 0 where a b in R then value of a is

If (1-i) is a root of the equation x^(2) +ax+b=0, then the values of a and b are-

If 2 - i is a root of the equation ax^2+ 12x + b=0 (where a and b are real), then the value of ab is equal to :

If 1-i is a root of the equation x^(2)+ax+b=0 , then b is equal to

If a and b are integers and 2-sqrt3 is a root of the equation 3x^2+ax+b =0, then value of b is

The roots of the equation ax^2+x+b=0 are equal if

If a and b are the roots of the equation x^2+ax+b=0 ,then a+b=
