[" If "a" and "b" are the non-zero distinct roots of "x^(2)+ax+b],[=0," then the least value of "x^(2)+ax+b" is "]

If a and b are the non-zero distinct roots of x^(2) + ax + b =0 , then the minimum value of x^2 + ax + b is

If a and b are the non-zero roots of the equation x^(2) + ax + b = 0 , then the least value of the expression x^(2) + ax + b is

If a and b ( != 0) are roots of x^(2) +ax + b = 0 , then the least value of x^(2) +ax + b ( x in R) is :

If a and b(!=0) are the roots of the equation x^(2)+ax+b=0 then the least value of x^(2)+ax+b is

If a and b(!=0) are the roots of the equation x^(2)+ax+b=0, then find the least value of x^(2)+ax+b(x in R)

If a and b(!=0) are the roots of the equation x^2+ax+b=0 then the least value of x^2+ax+b is
