For this case we must factor the following expression:
![4x ^ 3 + x ^ 2-8x-2](https://tex.z-dn.net/?f=4x%20%5E%203%20%2B%20x%20%5E%202-8x-2)
We group the first two and the last two terms:
![(4x ^ 3 + x ^ 2) + (- 8x-2)](https://tex.z-dn.net/?f=%284x%20%5E%203%20%2B%20x%20%5E%202%29%20%2B%20%28-%208x-2%29)
We factor the highest common denominator of each group:
![x ^ 2 (4x + 1) -2 (4x + 1)](https://tex.z-dn.net/?f=x%20%5E%202%20%284x%20%2B%201%29%20-2%20%284x%20%2B%201%29)
We take the common factor![4x + 1:](https://tex.z-dn.net/?f=4x%20%2B%201%3A)
![(4x + 1) (x ^ 2-2)](https://tex.z-dn.net/?f=%284x%20%2B%201%29%20%28x%20%5E%202-2%29)
Answer:
![(4x + 1) (x ^ 2-2)](https://tex.z-dn.net/?f=%284x%20%2B%201%29%20%28x%20%5E%202-2%29)
Answer: 105

Answer:
D
Step-by-step explanation:
I took an educated guess, I remember doing this.
Question 5 is C
To find how much she made from her sales, we multiply her sales by the decimal from of the commission.
32000*0.08 = 2560
Then we add this to her base pay (2560+1500) to get 4060
Question 6 is B
First, you can distribute the 1/2 to get 2-y
Then you can combined all terms that have a y
Your final answer is -3(1/2)+2
