It makes it much easier now that it's factored.
The solutions for n can be found when the equation equals zero.
What values does n take when 3n(2n-5)(n+1)=0?

Are you asking how did they come to the answer?

anonymous · Answer

IF that is the case - bring out the common factor from each term 
then factor what is left...
