यदि \(q=\sqrt{3}+2\) है तो \(q^2-4q\) का मान क्या है?
If \(q=\sqrt{3}+2\), what is the value of \(q^2-4q\)?
Explanation opens after your attempt
A. (-1)
Concept
\(q^2=7+4\sqrt{3}\) and \(4q=8+4\sqrt{3}\). Subtracting gives (-1).
Why this answer is correct
The correct answer is A. (-1). \(q^2=7+4\sqrt{3}\) and \(4q=8+4\sqrt{3}\). Subtracting gives (-1).
Exam Tip
\(q^2=7+4\sqrt{3}\) और \(4q=8+4\sqrt{3}\) है। घटाने पर (-1) मिलता है।
