1/(c-3)-1/c=3/c(c-3)
We move all terms to the left:
1/(c-3)-1/c-(3/c(c-3))=0
Domain of the equation: (c-3)!=0
We move all terms containing c to the left, all other terms to the right
c!=3
c∈R
Domain of the equation: c!=0
c∈R
Domain of the equation: c(c-3))!=0We calculate fractions
c∈R
We do not support ecpression: c^3
