For this case we have the following polynomials:

By subtracting both polynomials we have:

What we must do is subtract terms of the same degree.
We have then:
Answer:
will be a polynomial
Answer:
You can rewrite it to figure out the square root of 20 which would give you the value 4.47214...
Step-by-step explanation:
Answer:
infinite
Step-by-step explanation:
if you graph the equation it would overlap.
overlap = infinite
parallel = no solution
intersect = one solution
I believe the correct answers are A, B, and D
