Answer:
this is prime
Step-by-step explanation:
For determining the correct degree of a polynomial, you need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.
Classification by the number of terms:
monomial<span> (1 term)
</span>binomial<span> (2 terms)
</span>trinomial<span> (3 terms)
</span>polynomial (<span>four or more terms</span>).
Step-by-step explanation:
x^2 = 16
x = ±4
x^2 = -16
x = -
as a negative number cannot be squareroot
