![#5 (Constructing Arguments)
Explain WHY the nature of the roots occur the way they
do based on The Discriminant. Specifically, explain why:
· there are 2 RATIONAL roots when D > 0 and = a
perfect square
· there are 2 IRRATIONAL roots when D > 0 but +
a perfect square
· there is 1 RATIONAL root when D = 0
· there are 2 IMAGINARY/COMPLEX roots when D
< 0.
