Iam desperate 98 point for the person who answers this right polynomials are a close/not closed system under addition and subtraction as are whole numbers and integers/all number/monomial/whole number. when you add or subtract polynomials you end up with other polynomial/whole number/integers/binomials.

The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Consequently, polynomials are closed under multiplication. Polynomials are NOT closed under division.

Step-by-step explanation:

Example

What's the degree of the following polynomials?

x2+x

The first monomial has a degree of 2 and the second monomial has a degree of 1. The highest degree is 2 which mean that the degree of the polynomial is 2.

x4+x2+x

4, 2 and 1 , the highest degree is 4 which mean that the degree of the polynomial is 4.

We can add and subtract polynomials. We just add or subtract the like terms to combine the two polynomials into one.

its the first one

Step-by-step explanation:

becuase it tells more explanation if you look at the answer or what im saying is problem to make it more simpler.
