Solution for R(x)=x(x-2)/(x-3)(x+1) equation:



(R)=R(R-2)/(R-3)(R+1)
We move all terms to the left:
(R)-(R(R-2)/(R-3)(R+1))=0
Domain of the equation: (R-3)(R+1))!=0
R∈R
We multiply parentheses ..
-(R(R-2)/(+R^2+R-3R-3))+R=0
We multiply all the terms by the denominator
-(R(R-2)+R*(+R^2+R-3R-3))=0
We calculate terms in parentheses: -(R(R-2)+R*(+R^2+R-3R-3)), so:
R(R-2)+R*(+R^2+R-3R-3)
determiningTheFunctionDomain R*(+R^2+R-3R-3)+R(R-2)
We multiply parentheses
R^3+R^2-3R^2+R^2-3R-2R
We do not support eRpression: R^3
