\[x^3-12 x^2+32 x \]

\[(x-0)(x-4)(x-8)\]Multiply them.

generally an equation of the form:
\[(x-c_1)(x-c_2)...(x-c_n)=0\]where all the "c" terms are constants means that the "c" terms are all the solutions of tis equation.
using this you should be able to work out the answer you want.

OpenStudy (asnaseer):
look at what I typed out - that should give you a BIG hint
OpenStudy (anonymous):
it says its wrong ):
OpenStudy (asnaseer):
sigh...it should be:
(x-0)(x-4)(x-8)=0
which simplifies to:
x(x-4)(x-8)=0

And then finally to answer i wrote.
OpenStudy (anonymous):
ur right saifoo... my homework much just be stupid
OpenStudy (asnaseer):
which expands to:
\[x^{3}-12x^{2}+32x=0\]
you omitted the "= 0" on the RHS.
