यदि \(x^2+px+q=0\) के मूल (4) और (p) हैं, तो (p) का मान क्या होगा?
If the roots of \(x^2+px+q=0\) are (4) and (p), what is the value of (p)?
Explanation opens after your attempt
Correct Answer
A. (-2)
Concept
The sum of roots is (4+p), and in the equation the sum is (-p). Thus (4+p=-p), giving (p=-2).
Why this answer is correct
The correct answer is A. (-2). The sum of roots is (4+p), and in the equation the sum is (-p). Thus (4+p=-p), giving (p=-2).
Exam Tip
मूलों का योग (4+p) है और समीकरण में योग (-p) होता है। इसलिए (4+p=-p), जिससे (p=-2) मिलता है।
