यदि \(x^2+px+q=0\) के मूल (-3) और (-4) हैं तो (p+q) का मान क्या है?
If roots of \(x^2+px+q=0\) are (-3) and (-4), what is the value of (p+q)?
Explanation opens after your attempt
Correct Answer
A. (19)
Concept
The sum of roots is (-7), so (p=7), and the product gives (q=12). Hence (p+q=19).
Why this answer is correct
The correct answer is A. (19). The sum of roots is (-7), so (p=7), and the product gives (q=12). Hence (p+q=19).
Exam Tip
मूलों का योग (-7) है इसलिए (p=7) और गुणनफल (q=12) है। अतः (p+q=19) है।
