\(x^2-2\sqrt{11}x+11=0\) का मूल क्या है?
What is the root of \(x^2-2\sqrt{11}x+11=0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=\sqrt{11}\)
Concept
(\(x-\sqrt{11}\)2=0), so the repeated root is \(\sqrt{11}\). In exams, ((x-a)2=0) gives (x=a).
Why this answer is correct
The correct answer is A. \(x=\sqrt{11}\). (\(x-\sqrt{11}\)2=0), so the repeated root is \(\sqrt{11}\). In exams, ((x-a)2=0) gives (x=a).
Exam Tip
(\(x-\sqrt{11}\)2=0), इसलिए दोहराया हुआ मूल \(\sqrt{11}\) है। परीक्षा में ((x-a)2=0) से (x=a) मिलता है।
