यदि द्विघात समीकरण के मूल (4) और \(\frac{1}{4}\) हैं तो उनके बारे में सही कथन कौन सा है?
If the roots of a quadratic equation are (4) and \(\frac{1}{4}\), which statement is correct about them?
Explanation opens after your attempt
Correct Answer
A. वे एक दूसरे के व्युत्क्रम हैंThey are reciprocals of each other
Concept
\(4\cdot\frac{1}{4}=1\), so the roots are reciprocals. Reciprocal roots have product (1).
Why this answer is correct
The correct answer is A. वे एक दूसरे के व्युत्क्रम हैं / They are reciprocals of each other. \(4\cdot\frac{1}{4}=1\), so the roots are reciprocals. Reciprocal roots have product (1).
Exam Tip
\(4\cdot\frac{1}{4}=1\) है इसलिए दोनों व्युत्क्रम मूल हैं। व्युत्क्रम मूलों का गुणनफल (1) होता है।
