b2-4ac.
Discriminant formula: D = b^2 - 4ac
b2-4ac
D*d=b*b-4ac
discriminant
The discriminant
The coefficients are a = 4, b = -3, c = -8. The discriminant is calculated with the formula b2 - 4ac, so just replace the coefficients in this formula.

No.
yes
The discriminant formula. b2 - 4ac 32 - 4(1)(8) 9 - 32 = - 23 ===========This shows no real roots to this function.
If the discriminant of b2-4ac in the quadratic equation formula is less than zero then the equation will have no real roots.
