Explain the closure property as it relates to polynomials. give an example. (5 points)

When adding/subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the sum/difference has variables and exponents which are already classified as belonging to polynomials. So polynomials are closed under addition/subtraction.

I hope my answer has come to your help. God bless and have a nice day ahead!

Closure property is when two or more polynomials are either added or subtracted from each other, the result will always be a polynomial.
