voice can be bit more louder..
Since the result in step 3 when we subtract a^2 from both side will be zero.Hence any further operations are meaningless.
ab-a^2will be equal to zero
i'm getting confusion with componendo and divedendo if we add 1 means its componendo and if we subract 1 from ratio then its called dividendo please correct me if i'm wrong
