First, eliminate the radical. So, take the square of both sides of the equation.



Then, remove the x in the denominator. To do so, multiply the equation by x-c.



Next, bring together the terms with x on one side of the equation. So, subtract both sides by x.



Also, add both sides by a^2c to bring together the terms without x on the other side of the equation.



Then, factor out the GCF at the left side.


And to have x only at the left, divide both sides by a^2-1.



Hence, `x=(a^2c+c)/(a^2-1)` .
