Assertion (A): If a^2 - 8a - 1 = 0. ⇒ a^2/a - 8a/a - 1/a = 0 ⇒ a - 1/a = 8 is not true. Reason (R): The division of each term of the equation a^2 - 8a - 1 = 0 is defined only when a is not equal to 0 (zero). 1. A is true, R is false. 2. A is false, R is true. 3. Both A and R are true. 4. Both A and R are false.
