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
Correct Answer

A. (3)

Step 1

Concept

For equal roots (D=0), so (62-4(m)(3)=0). This gives (m=3).

Step 2

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).

Step 3

Exam Tip

समान मूलों के लिए (D=0) है इसलिए (62-4(m)(3)=0)। इससे (m=3) मिलता है।
