(3(x+1))/(x^2-1)=1

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

(3(x+1))/(x^2-1)=1

We move all terms to the left:

(3(x+1))/(x^2-1)-(1)=0


Domain of the equation: (x^2-1)!=0

We move all terms containing x to the left, all other terms to the right

x^2!=1

x^2!=1/

x^2!=√1/

x!=1

x∈R


We multiply all the terms by the denominator


(3(x+1))-1*(x^2-1)=0


We calculate terms in parentheses: +(3(x+1)), so:

3(x+1)

We multiply parentheses

3x+3

Back to the equation:

+(3x+3)


We get rid of parentheses

3x-1*(x^2-1)+3=0
