It is 40.

That will depend on the value of 10 which has not been given but in general if the discriminant is less than zero then the quadratic has no real roots
It is: 16-20 = -4 which means that the given quadratic expression has no real roots.
The discriminant of x^2 + 6 - 16 = discriminant of x^2 - 10 is 40.
It is 40.

12
That will depend on the value of 10 which has not been given but in general if the discriminant is less than zero then the quadratic has no real roots
It is 36.
It is: 16-20 = -4 which means that the given quadratic expression has no real roots.
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
The discriminant is 9.
The discriminant of x^2 + 6 - 16 = discriminant of x^2 - 10 is 40.
The discriminant of x2+3x+4 is -7 therfore it has no real roots.
It is 0.
