Let's try an example:
The difference between (6x3 + x2 - 4x + 9) and (6x3 + x2 - 4x + 7) is 2 .
2 is a polynomial of degree 0, so this example would appear to support the hypothesis in the question.
However, polynomials cannot include negative exponents. So, (2x)/(2x2) produces 1/x, which is not a polynomial.
So no, not always.
Closure
The sum of two polynomials is always a polynomial. Therefore, it follows that the sum of more than two polynomials is also a polynomial.
No. Even if the answer is zero, zero is still a polynomial.

That property is called CLOSURE.

Yes. A polynomial multiplying by a polynomial will always have a multi-termed product. Hope this helps!
It is called the property of "closure".
That property is called CLOSURE.
Division of one polynomial by another one.
A zero of the derivative will always appear between two zeroes of the polynomial. However, they do not always alternate. Sometimes two or more zeroes of the derivative will occur between two zeroes of a polynomial. This is often seen with quartic or quintic polynomials (polynomials with the highest exponent of 4th or 5th power).
prime
Yes. Note that specifically, the sum might be a constant (just a number), or even zero, but it is convenient to include those in the definition of "polynomial".
Two terms is a binomial. More than two terms is a polynomial. Binomials are not part of the set of polynomials.
