यदि \(mx^2+6x+3=0\) के मूल समान हैं तो (m) का मान क्या होगा?
If the roots of \(mx^2+6x+3=0\) are equal, what will be the value of (m)?
Explanation opens after your attempt
A. (3)
Concept
For equal roots (D=0), so (62-4(m)(3)=0). This gives (m=3).
Why this answer is correct
The correct answer is A. (3). For equal roots (D=0), so (62-4(m)(3)=0). This gives (m=3).
Exam Tip
समान मूलों के लिए (D=0) है इसलिए (62-4(m)(3)=0)। इससे (m=3) मिलता है।
