Answer:
Q(-10) = 299
Step-by-step explanation:
![Q(x) = 3x^{2} - 1](https://tex.z-dn.net/?f=Q%28x%29%20%3D%203x%5E%7B2%7D%20-%201)
![Q(-10) = 3(-10)^{2} - 1](https://tex.z-dn.net/?f=Q%28-10%29%20%3D%203%28-10%29%5E%7B2%7D%20-%201)
(-10 to the second power is 100 (negative times a negative equals a positive)
3 times 100 equal 300
![Q(-10) = 299](https://tex.z-dn.net/?f=Q%28-10%29%20%3D%20299)
Answer:
The numerator factors to
![(x + 2)(x - 1)](https://tex.z-dn.net/?f=%28x%20%2B%202%29%28x%20-%201%29)
The denomenator factors to
![(x + 4)(x - 1)](https://tex.z-dn.net/?f=%28x%20%2B%204%29%28x%20-%201%29)
