समीकरण \(x^2=4x\) के मूल कौन से हैं?
What are the roots of \(x^2=4x\)?
Explanation opens after your attempt
A. (0) और (4)(0) and (4)
Concept
Write \(x^2=4x\) as \(x^2-4x=0\). Then (x(x-4)=0) gives roots (0) and (4).
Why this answer is correct
The correct answer is A. (0) और (4) / (0) and (4). Write \(x^2=4x\) as \(x^2-4x=0\). Then (x(x-4)=0) gives roots (0) and (4).
Exam Tip
\(x^2=4x\) को \(x^2-4x=0\) लिखें। फिर (x(x-4)=0) से मूल (0) और (4) मिलते हैं।
