What are the roots of \(x^2+8x+5=0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=-4\pm\sqrt{11}\)
Concept
Since ((x+4)2=11), \(x=-4\pm\sqrt{11}\). In exams, write both values using \(\pm\).
Why this answer is correct
The correct answer is A. \(x=-4\pm\sqrt{11}\). Since ((x+4)2=11), \(x=-4\pm\sqrt{11}\). In exams, write both values using \(\pm\).
Exam Tip
((x+4)2=11), इसलिए \(x=-4\pm\sqrt{11}\) है। परीक्षा में \(\pm\) के दोनों मान लिखें।
