Answer:
Step-by-step explanation:
First, find the roots of the polynomial:
The roots are the values of (x) where (C(x) = 0).
Using the quadratic formula, we find that the roots are approximately (x_1 \approx -0.91) and (x_2 \approx 2).
Next, determine the intervals where (C(x)) is negative:
Evaluate (C(x)) at a point within each interval.
If (C(x)) is negative at that point, the interval satisfies the inequality.
The solution interval for (C(x) \leq 0) is approximately ((0.91, \infty)).
Therefore, the solution to the inequality (C(x) \leq 0) is: (x \in (0.91, \infty)).
