Question

I need help i cant remember how to do this!! :(
Which statement shows that when two polynomials 5x - 6 and 6x + 2 demonstrates the closure property when multiplied?

Answer 1

can you put the choices or clarify the question?

Answer 2

the closure property a + b is a real number; ab is a real number

(5x-6)(6x +2)
30x^2-36x + 10x -12
30x^2 + 10x -36x -12
10x(3x +1)-12(3x +1)
(10x -12)(3x + 1)
2(5x-6)(3x + 1)
