R(X)=X/(X-1)(x+2)

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

(R)=R/(R-1)(R+2)

We move all terms to the left:

(R)-(R/(R-1)(R+2))=0


Domain of the equation: (R-1)(R+2))!=0

R∈R


We multiply parentheses ..

-(R/(+R^2+2R-1R-2))+R=0

We multiply all the terms by the denominator


-(R+R*(+R^2+2R-1R-2))=0


We calculate terms in parentheses: -(R+R*(+R^2+2R-1R-2)), so:

R+R*(+R^2+2R-1R-2)

determiningTheFunctionDomain
R*(+R^2+2R-1R-2)+R

We multiply parentheses

R^3+2R^2-1R^2-2R+R

We do not support eRpression: R^3
