Answer:
Two
Step-by-step explanation:
The discriminant of a quadratic ax² + bx + c is b² − 4ac.
If the discriminant is negative, there are no real zeros.
If the discriminant is 0, there is one real zero.
If the discriminant is positive, there are two real zeros.
Here, a = 3, b = 12, and c = 5. The discriminant is:
(12)² − 4(3)(5)
144 − 60
84
The discriminant is positive, so there are two real zeros.
