Answer 2

What do you have with this problem so far?

Answer 3

What do you mean?

Answer 4

Theses are the answer choices:

2x2 − 4x + 2 will be a polynomial
2x2 − 4x + 2 may or may not be a polynomial
2x2 − 12x − 10 will be a polynomial
2x2 − 12x − 10 may or may not be a polynomial

I think it maybe either c or d
