Good morning, sir. I have a doubt in 16:50. In this part, under root 9 would give us +3, -3. If we put the value of -3, then our equation is not satisfied, the answer would be -6, instead. Would this be considered incorrect? Sir, similarly, in the next question, the value of under root 25 should be +5, -5. If we put the value of -5, then our equation is satisfied

Beta under root 9 =only 3, not -3 . You are thinking wrong.
