Answer:
Step-by-step explanation:
The quadratic expression can be factored into two binomials if it has two real roots.
<u>Two real roots possible with non-negative discriminant:</u>
As D = b² - 4ac, we get the following inequality
- k² - 4(3)(-8) ≥ 0
- k² + 96 ≥ 0
- k² ≥ - 96
This is true for any value of k
