Which statement justifies that 3x2 − 2x − 4 multiplied by 2x2 + x − 3 obeys the closure property of multiplication? The result 6
N76 [4]

Answer:

The result 6x^4-x^3-19x^2+2x+12.

is a polynomial.

Step-by-step explanation:

The first polynomial is 3x^2-2x-4.

The second polynomial is 2x^2+x-3

The closure property of multiplication states that if we multiply two polynomials the result must be a polynomial.

The product of these two polynomials is :

(3x^2-2x-4)(2x^2+x-3)=6x^4-x^3-19x^2+2x+12.

We can see that the result is still a polynomial.
