Answer:
Can't guess whether you have written 'x' or you have put a sign of multiplication!!
Answer:
Which i think is the first one, there may just be a typing error.
Step-by-step explanation:
A polynomial of order n has the following format:

In which a is the leading coefficient,
are the roots.
If a root appears m times, they are said to have multiplicity m.
Leading coefficient of 1 and roots 21 and 31 with multiplicity 1

So the correct answer is:

Which i think is the first one, there may just be a typing error.
Answer:
1152 or 1200 is the answer I don’t know which one though.
Step-by-step explanation:
Answer:
Degree of the polymonial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.
Step-by-step explanation:
I think the equation is 4m² – 3
Therefore, degree of the polynomial is the sum of the powers of the variables,
2 + 6 + 4 = 12
Hope this helps!
