Part a: create a fourth-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 polynomials. give an example. (5 points) show all work !

A. polynomials is standard form are written with their degrees arranged from left to right (highest degree to lowest degree)example: 4x^4+ 2x^3 + 6x^2 + 5x -7this is a fou degree polynomial written in standard form.b. the closure property means that they are closed in addition, subtraction just like integers. i.e. their degrees dont change under addition and subtractionexample: (3x^3 + 4x ) + (6x^4 - x)= 3x^3 + 4x + 6x^4 - x= 3x^3 + 3x + 6x^4

That’d be 9 years or something
