Which statement shows how two polynomials 5x − 6 and 6x + 2 demonstrate the closure property when multiplied?
A: 30x2 − 26x − 12 may or may not be a polynomial
B:30x2 − 11x − 12 may or may not be a polynomial
C:30x2 − 26x − 12 is a polynomial
D:30x2 − 11x − 12 is a polynomial

Definition of Polynomial : A mathematical expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a non negative integral power is called a polynomial.

So, Option C is true.
