Question

Which statement shows how two polynomials 5x − 6 and 6x + 2 demonstrate the closure property when multiplied?


30x2 − 26x − 12 may or may not be a polynomial

30x2 − 11x − 12 may or may not be a polynomial

30x2 − 26x − 12 is a polynomial

30x2 − 11x − 12 is a polynomial

Answer 1

closure says:

take any two items in a set and perform an operation on them. If you get an item that is also in the set, then the set is closed under that operation

Answer 2

example

take the set of integers and pick any two integers from that set. Multiplying them gives you another integer. Therefore, the set of integers is closed under multiplication
