Factor out :
= .
Now solve this polynomial equation:
= .
Its 3 roots are x = 0 of multiplicity 3.
Next you need to solve this quadratic equation
= .
Notice that the left side is .
So, your equation is
= .
It has the root x = 3 of multiplicity 2.
Answer. The roots are x=0 of multiplicity 3 and x=3 of multiplicity 2.
