Answer:
No it's not
Step-by-step explanation:
It is the square root of a polynomial, but it is not a polynomial itself… in this case.
Of course, there are square roots of polynomials that are polynomials themselves. For instance, x2−6x+9−−−−−−−−−√ is the polynomial x−3 (or is it 3−x ?) But there is no polynomial whose square is x−1 .
