यदि \(q=\sqrt{3}+1\) है, तो \(q^2-2q\) का मान क्या है?
If \(q=\sqrt{3}+1\), what is the value of \(q^2-2q\)?
Explanation opens after your attempt
A. (2)
Concept
\(q^2=4+2\sqrt{3}\) and \(2q=2\sqrt{3}+2\). Subtracting gives (2).
Why this answer is correct
The correct answer is A. (2). \(q^2=4+2\sqrt{3}\) and \(2q=2\sqrt{3}+2\). Subtracting gives (2).
Exam Tip
\(q^2=4+2\sqrt{3}\) और \(2q=2\sqrt{3}+2\) है। घटाने पर (2) मिलता है।
