I did that and got B. But B was wrong.

ivettef365 · Answer

Well do the multiplication using distributive property
(6z^2)(8) = 48z^2
(6z^2)(-3z) = -18z^3
Now keep on with (-4z)(8-3z)
and then ((1) (8-3z)
then add all the results

ivettef365 · Answer

not really

anonymous · Answer

(8 - 3z)(6z2-4z+1)
48z2-32z+8-18z3+12z2+3z
now solve further!
the answer is tha last option!

anonymous · Answer

Farhreen could you illustrate that further? I'm not sure I understand.

anonymous · Answer

@ivettef365 using your theory I got 48z^2 - 18z^3 - 32z + 12z

anonymous · Answer

Is that right?

anonymous · Answer

BTW  i meant 48z2-32z+8-18z3+12z2-3z the first equation is wrong.
