Polynomials will be closed under an operation if the operation produces another polynomial. When multiplying polynomials, the variables' exponents are added, according to the rules of exponents.

You can only add x terms together only if they have the same exponent. For example you can add 2x^2 and x^2 but you cannot add x^2 and x^3.
In this particular problem, you can add 4x^4 and x^4, and x and 8x. So,
<span>
(x + 4x^4) + (x^4 - 2 + 8x)
</span>= 5x^4 + 9x -2
