यदि \(x^2+px+q=0\) के मूल (p) और (q) ही हैं, तो कौन-सा संबंध सही है?
If the roots of \(x^2+px+q=0\) are (p) and (q) themselves, which relation is correct?
Explanation opens after your attempt
Correct Answer
A. (p+q=-p) और (pq=q)(p+q=-p) and (pq=q)
Concept
The sum of roots is (-p) and the product is (q). Since the roots are (p,q), we get (p+q=-p) and (pq=q).
Why this answer is correct
The correct answer is A. (p+q=-p) और (pq=q) / (p+q=-p) and (pq=q). The sum of roots is (-p) and the product is (q). Since the roots are (p,q), we get (p+q=-p) and (pq=q).
Exam Tip
मूलों का योग (-p) और गुणनफल (q) होता है। दिए मूल (p,q) हैं, इसलिए (p+q=-p) और (pq=q)।
