Explanation opens after your attempt
Correct Answer
A. \(13-2\sqrt{22}\)
Concept
\(x^2=11+2-2\sqrt{22}=13-2\sqrt{22}\). In exams do not forget the middle term of ((a-b)2).
Why this answer is correct
The correct answer is A. \(13-2\sqrt{22}\). \(x^2=11+2-2\sqrt{22}=13-2\sqrt{22}\). In exams do not forget the middle term of ((a-b)2).
Exam Tip
\(x^2=11+2-2\sqrt{22}=13-2\sqrt{22}\) है। परीक्षा में ((a-b)2) का मध्य पद न भूलें।
