Question

4z^3 - 8z^2 = 0
solve for x

Answer 1

I think you mean "solve for z"?

start by factoring

Answer 2

can't wait to see the answer to this

Answer 3

Z

Answer 4

I meant z, sorry :p

Answer 5

anyway, start by identifying the greatest common factor of 4z^2 and 8z^2

Answer 6

*4z^3 and 8z^2

Answer 7

4z^2(z - 2) = 0
right?

Answer 8

excellent! now we split it into two parts

4z^2 = 0
and
(z-2) = 0

solve for z in both instances

Answer 9

z = 2
z = 0 :D
