First you want to reduce the brackets
Next you want to factor out the common number 3
Next you want to factor 20 + x^3 + 11x - 8x^2 by using the polynomial division method/technique
Lastly you just factor x^2 - 9x + 20 to get the answer.
Yes you are correct, the solutions are 1, 4, and 5.
Answer:
<em>D.) It has a common difference of 3.8</em>
Step-by-step explanation:
When you subtract 
you get a common difference, the same goes for the other values: when you subtract the previous term from the next, you get a common difference of positive 3.8
