Question

Which statement shows two polynomials 4x+6 and 2x^2-8x demonstrating the closure property when multiplied?

a.)8x^3-20x^2-48x is a polynomial
b.)8x^3+20x^2+48x may or may not be a polynomial
c.)8x^2-32x^2-14x is a polynomial
d.)8x^2+32x^2+14x may or may not be a polynomial

Answer 1

It's Option A 8x^3-20x^2-48 is a polynomial

Explanation:

I took the test and it was right

Answer 2

The correct answer for the given mathematical question above would be option A. The statement that shows two polynomials 4x + 6 and 2x^2-8x demonstrating the closure property when multiplied is that, 8x^3-20x^2-48x is a polynomial. The answer is option A for the given reason: (4x+6)(2x^2 -8x)= 8x^3 -20x^2 -48x
