D. Subtraction
2. The difference of two polynomials must always result in a _____.
A. Polynomial
B. Monomial
C. Binomial
D. Trinomial
3. Can a binomial be multiplied by a monomial such that the product is a monomial? If so, give an example.
A. Yes. 2(2x+y)=4x+2y
B. Yes. 0(2x+y)=0
C. No. A binomial can never be multiplied by a monomial such that the product is a monomial.

please answer all of them

1. Polynomials are not closed under the operation of C. division. Dividing one polynomial by another may result in a quotient that is not a polynomial.

2. The difference of two polynomials must always result in a A. Polynomial.
3. Yes. A monomial can be multiplied by a binomial to give a monomial. An example is given in option A. 2(2x+y)=4x+2y.
4. Yes. Two polynomials can be subtracted such that the difference is a binomial. An example is given in option C. (3b^2−3b)−(b+a+3).
5. Yes. Two polynomials can be subtracted such that the difference is a trinomial. An example is given in option D. (3x+3)−(3x+2y+3).
