यदि \(x^2+px+q=0\) के मूल (5) और (p) हैं, तो (p) का मान क्या होगा?
If the roots of \(x^2+px+q=0\) are (5) and (p), what is the value of (p)?
Explanation opens after your attempt
Correct Answer
A. -\(\frac{5}{2}\)
Concept
The sum of roots is (5+p), and in the equation the sum is (-p). Thus (5+p=-p), giving \(p=-\frac{5}{2}\).
Why this answer is correct
The correct answer is A. -\(\frac{5}{2}\). The sum of roots is (5+p), and in the equation the sum is (-p). Thus (5+p=-p), giving \(p=-\frac{5}{2}\).
Exam Tip
मूलों का योग (5+p) है और समीकरण में योग (-p) होता है। इसलिए (5+p=-p), जिससे \(p=-\frac{5}{2}\) मिलता है।
