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

First tell me; which of the following statements are true -
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 2

Ummm, the first one I guess...

Answer 3

Do you know the definition of polynomial ??

Answer 4

Yes, it's one or more terms.

Answer 5

So all of them?

Answer 6

Or maybe C and D??

Answer 7

Only C and D are correct as the expression is definitely a polynomial.

Now, can you tell me what is (5x-6)*(6x+2)

Answer 8

30x^2-26x-12 I think...

Answer 9

So, what do you think should be the final answer ??

Answer 10

C.

Answer 11

Yep :)

Answer 12

Thanks I appreciate it.

Answer 13
