\(x^2+4x+1=0\) के मूल क्या हैं?
What are the roots of \(x^2+4x+1=0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=-2\pm\sqrt{3}\)
Concept
Since ((x+2)2=3), \(x=-2\pm\sqrt{3}\). In exams, write both values using \(\pm\).
Why this answer is correct
The correct answer is A. \(x=-2\pm\sqrt{3}\). Since ((x+2)2=3), \(x=-2\pm\sqrt{3}\). In exams, write both values using \(\pm\).
Exam Tip
((x+2)2=3), इसलिए \(x=-2\pm\sqrt{3}\) है। परीक्षा में \(\pm\) के दोनों मान लिखें।
