Answer:
<em>The numbers between -5 and 5</em>
Step-by-step explanation:
Intersection of Intervals
Given the intervals A,B,C,etc. The intersection of them all is the set of all values that are common to all the intervals.
We must find

which is the intersection between the intervals x > -5 and x < 5. The intersection represents all the numbers greater than -5 and less than 5. It can also be said The numbers between -5 and 5 (non inclusive), third option
I believe it would be the first term over the last term, +/-, including the factors of both the last term, so:
for x^4:
1*4
2*2
for 12:
1*12
2*6
3*4
then divide all of this, and include the +/-'s of each. By divide, I mean take all the factors of the first term, aka the numerator, and those are possible rat. 0's. Then divide all those by the factors of the coefficient. Remove any duplicates.
