Data Sufficiency

I think I correctly attached the screenshot, if not, here's the problem:

Is it true that x>0?

(1) x^2=2x
(2) x^3=3x

for statement 1:

x(x-2) = 0

therefore, x = 0, 2 ---- INSUFFICIENT

statement 2:

x(x^2-3)=0 (THIS IS WHERE GMAT FOCUS IS WRONG -- they have, x^2(x-3) -- this factored would be x^3-3x^2 = 0, WRONG)

I obviously could be wrong, but from statement 2 I conclude that x = 0 or is a positive number --- INSUFFICIENT

COMBINING 1+2 =

x^2=2x
x^3=3x

I multiplied statement 1 by x, getting -- x^3=2x^2

Now, I substituted x^3 from statement 2.

3x = 2x^2

Then I did this:

3x-2x^2=0
x(3-2x)=0
x=0
x=3/2

ANSWER E -- GMATFOCUS says Answer C

What say you Beatthegmat??
