(3/x+20)-(4/x-20)=(4x/x^2-400)
We move all terms to the left:
(3/x+20)-(4/x-20)-((4x/x^2-400))=0
Domain of the equation: x+20)!=0
x∈R
Domain of the equation: x-20)!=0
x∈R
Domain of the equation: x^2-400))!=0We get rid of parentheses
x∈R
3/x-4/x-((4x/x^2-400))+20+20=0
We calculate fractions
We do not support expression: x^3
