Which statement justifies that 3x^2 - 2x - 4 multiplied by 2x^2 + x - 3 obeys the closure property of multiplication? The result 6x^4 - 2x^2 + 12 has a degree of 4. The result 6x^4 - 2x^2 + 12 is a trinomial. The result 6x^4 - x^3 - 19x^2 + 2x + 12 is a polynomial. The result 6x^4 - x^3 - 19x^2 + 2x + 12 has a degree of 4.

What does the closure property mean?

Since you have a question about the closure property, you need to know its meaning to be able to answer. I'll explain it to you.
The closure property means that if you do a certain operation with numbers from a set of numbers, the answer is also in the set of numbers.
I'll give you some examples to make it easier to understand.
The closure property is an attribute of a set with respect to a binary operation, not only a binary operation. A set S is closed with respect to multiplication if, for any two elements, x and y, belonging to S, x*y also belongs to S.
Question: Is there closure in the multiplication of two integers? Answer: if you multiply any two integers, the answer will be an integer. That means there is closure for multiplication of integers.
Question: Is there closure for subtraction of whole numbers? Answer: 3 and 7 are whole numbers. Since 3 - 7 = -4, and -4 is not a whole number, there is no closure for subtraction of integers.
Do you understand the idea of closure now?
Did you get the answer?
