Part A: Create a fifth-degree polynomial with four terms in standard form. How do you know it is in standard form? (5 points) Part B: Explain the closure property as it relates to subtraction of polynomials. Give an example. (5 points)

5x 3y^3 2z

Step-by-step explanation:

Part A:

I know it is in standard form because there are no more like terms.

Part B: Polynomials are always closed under multiplication. Unlike with addition and subtraction, both the coefficients and exponents can change. The variables and coefficients will automatically fit in a polynomial. When there are exponents in a multiplication problem, they are added, so they will also fit in a polynomial.
