The roots of the equation `x^(2) + ax + b = 0` are `"______"`.

If a and b are the roots of the equation x^(2) + ax + b = 0, a ne 0, b ne = 0 , then the values of a and b are respectively

The non-trival values of (a,b) such that roots of the equation x^(2) + ax + b = 0 are equal to a and b are :

If a and b are complex and one of the roots of the equation x^(2) + ax + b =0 is purely real whereas the other is purely imaginary, then

If a and b are complex and one of the roots of the equation x^(2) + ax + b =0 is purely real whereas the other is purely imaginary, then

If root of the equation x^(2) + ax + b = 0 are alpha , beta , then the roots of x^(2) + (2 alpha + a) x + alpha^(2) + a alpha + b = 0 are

tan23^(@) and tan22^(@) are the roots of the equation x^(2)+ax+b=0 then

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 alpha, beta are roots of the equation x^(2) + ax + b = 0 , then maximum value of - x^(2) + ax + b + (1)/(4) (alpha - beta )^(2) is

If sec alpha and cosec alpha are the roots of the equation x^(2)-ax+b=0, then
