Answer:
Alternative C - Has two unequal real roots and two unequal complex roots
Step-by-step explanation:
The roots of this equation are:
(solved using the computer):
[tex]1,\text{ -1, }\frac{1-i\sqrt[]{3}}{2},\text{ }\frac{1+i\sqrt[]{3}}{2}[/tex]As we can see, we have two unequal real roots and two unequal complex roots.
Alternative C.
