समीकरण \(x^2-8x+m=0\) में समान वास्तविक मूलों के लिए (m) क्या होगा?
In \(x^2-8x+m=0\), what is (m) for equal real roots?
Explanation opens after your attempt
Correct Answer
A. (16)
Concept
(D=(-8)2-4m=0) gives (m=16). Keep the discriminant zero for equal roots.
Why this answer is correct
The correct answer is A. (16). (D=(-8)2-4m=0) gives (m=16). Keep the discriminant zero for equal roots.
Exam Tip
(D=(-8)2-4m=0) से (m=16) मिलता है। बराबर मूलों के लिए विविक्तकर शून्य रखें।
