Question

Which statement shows how two polynomials 4x + 6 and 2x2 − 8x demonstrate the closure property when multiplied?

a. 8x3 − 20x2 − 48x is a polynomial

b. 8x3 − 20x2 + 48x may or may not be a polynomial

c. 8x2 − 32x2 − 14x is a polynomial

d. 8x3 − 32x2 + 14x may or may not be a polynomial

Answer 1

when you multiply out you get \(8 x^3-20 x^2-48 x\)
go with A since it is certainly a polynomial

Answer 2

a. 8x3 − 20x2 − 48x is a polynomial
