Question

100 POINTS!!!! Please be quick and make sure you have a correct answer, no plagiarizing, and no silly answers. Will give BRAINLIEST!
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)

Answer 1

Part A

5x 3y^3 2z

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.

Answer 2

Answer:

A: 3x^2 + 4y^5 - 3. I know it's in standard form because I cannot simplify it anymore.

B:  When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change.  the variables and exponents will only change with multiplication and division.
