यदि \(2x^2+mx+8=0\) में मूलों का योग (-3) है, तो (m) क्या है?
If the sum of roots of \(2x^2+mx+8=0\) is (-3), what is (m)?
Explanation opens after your attempt
A. (6)
Concept
The sum of roots is \(-\frac{m}{2}=-3\), so (m=6). Notice the negative sign in the sum formula.
Why this answer is correct
The correct answer is A. (6). The sum of roots is \(-\frac{m}{2}=-3\), so (m=6). Notice the negative sign in the sum formula.
Exam Tip
मूलों का योग \(-\frac{m}{2}=-3\), इसलिए (m=6) है। योग के सूत्र में ऋण चिन्ह पर ध्यान दें।
