Step-by-step explanation:
![[ \ x^ 2- 1 = (x-1)(x + 1) \ ]](https://tex.z-dn.net/?f=%5B%20%5C%20x%5E%202-%201%20%3D%20%28x-1%29%28x%20%2B%201%29%20%5C%20%5D)
![[\ Taking \ LCM \ ]](https://tex.z-dn.net/?f=%5B%5C%20Taking%20%5C%20LCM%20%5C%20%20%5D)

<em><u>Finding LCM :</u></em>
Example :
6 = 2 x 3
3 = 1 x 3
[ To make the denominators same : the second fraction is multiplied and divided by 2 ]
Similarly :

Same rule we applied : multiplied the numerator and denominator of the second term with ( x - 1 )
Therefore the second term becomes ,
