Part a: create a third-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: standard form refers to the order of terms in a polynomial.a polynomial is considered to be in standard form if the degrees are listed from highest to lowest from left to right.a third-degree polynomial means that the biggest degree the polynomial will have is 3. a term must have x raised to the 3rd power. an example polynomial with a degree of 3 is the following expression: this polynomial is in standard form, as the term with the degree of 3 is the first term on the left. the degrees are descending as you go further right on the expression.b: closure property relates to addition of polynomials in which that two polynomials added together will always result in a polynomial.an example operation that fits under closure property is the following: the sum is a polynomial, which makes this closure property valid.
