You can
put this solution on YOUR website!If your equation has the form

etc.
then

,

,

etc. are the zeroes
The multiplicity is the number of times a zero is repeated,
for instance:

etc.
Zero

has a multiplicity of

, since it's
repeated

times
In your equation:

, I can factor it some more:

The zeroes are

multiplicity of

and

multiplicity of
