A set that is closed under an operation or collection of operations is said to satisfy a closure
property.
For example, the set of even integer is closed under addition, but the set of odd integer is not.
Answer:

Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like
. Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial,
, which equals
. - Then, the outside terms,
. This equals
. - Next, the inside terms,

. - Finally, the last terms,
, this equals
.
Then, add all of the terms together
. To get the standard form, combine like terms, this comes out to
.
