Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is
![F(x)=x^4+x^3-5x^2+x-6](https://tex.z-dn.net/?f=F%28x%29%3Dx%5E4%2Bx%5E3-5x%5E2%2Bx-6)
There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
Time = distance / speed
time = 621 / 51.75
time = 12 hrs <====
