Question 1189986: Have I determined the correct discriminant using b^2- 4ac to determine the nature of the roots to the 3 equations below? (Determined the nature of the roots of the below quadratic equations)
Equation 1:
x^2 + 5x + 8 = 0 This one has 2 complex roots
Equation 2:
3x^2 + x - 1 = 0 This one has 2 real roots
Equation 3:
x^2 - 4x = -8 This one has 2 complex roots
