\(x^2-8x+15=0\) के मूल पूर्ण वर्ग विधि से क्या मिलेंगे?
What roots are obtained for \(x^2-8x+15=0\) by completing the square method?
Explanation opens after your attempt
Correct Answer
A. (x=3,5)
Concept
Since ((x-4)2=1), \(x-4=\pm1\), so (x=3,5). In exams, use \(\pm\) to find both roots.
Why this answer is correct
The correct answer is A. (x=3,5). Since ((x-4)2=1), \(x-4=\pm1\), so (x=3,5). In exams, use \(\pm\) to find both roots.
Exam Tip
((x-4)2=1), इसलिए \(x-4=\pm1\) और (x=3,5) हैं। परीक्षा में \(\pm\) से दोनों मूल निकालें।
