Question

Which statement shows that when two polynomials 5x − 6 and 6x + 2 demonstrates 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

If you work the problem out, the answer is 30x^2 - 26x - 12. That narrows it down to A. and C.

Answer 2

30x^2 - 26x - 12 is under the branch of polynomials because it is a trinomial; a type of polynomial. The closure property states that the product of two polynomials will always be a polynomial.

Answer 3

The answer is C.

Answer 4

Thank you very much! It makes more sense now!
