Question

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

Answer 1

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 2

I don't know. sorry!

Answer 3

what do you think it is @bangbang559

Answer 4

I have no idea... that's why I need your help

Answer 5

a or c

hey @Awesome781 @beccaboo333 @Compassionate what do you think

Answer 8

how do you know its a? @sourwing

Answer 9

Sorreh I do not know.

Answer 10

you have a quadratic multiply by a linear, so the result is a cubic. And a cubic is a polynomial

Answer 11

I think @sourwing is correct

Answer 12

I just sumited the answer a and @sourwing was right :)

Answer 13

I am with sourwing but not that reason, to me, the answer is a because (4x+6)(2x^2 -8x)= 8x^3 -20x^2 -48x
dat sit

Answer 14

all of them are polynomials.

Answer 15

thank you all so much for your help I really appreciate it :)
