-7

It is: 25-4(8*6) = -167

The discriminant of x^2 + 6 - 16 = discriminant of x^2 - 10 is 40.

The discriminant is 9.

A discriminant that is less than zero.

Discriminant = b2-4ac = (-2)2-(4*4*4) = -60

If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.

The discriminant is b2 - 4ac. In this case, a = 1, b = 7, and c = 2. Just replace and calculate.

No real roots

The discriminant is 0.

There are no solutions because the discriminant is less than zero

Discriminant = (b2-4ac) = (25 - 4x2x3) = 1

It has no solutions because the discriminant of the quadratic equation is less than zero.

It can not be factored because its discriminant is less than zero

None because the discriminant is less than zero
