Part a: create a fifth-degree polynomial in standard form. how do you know it is in standard form? (5 points) part b: explain the closure property as it relates to addition of polynomials. give an example. (5 points)

A.

A polynomial in standard form has the terms written in order of decreasing degree.

6x^5 + 4x^4 - 2x^3 + 7x^2 + 13x + 8

B.

Polynomials are closed under addition. This means that if you add any two polynomials, the result is a polynomial.
