किस समीकरण के दोनों मूल विपरीत संख्याएँ होंगे?
Which equation will have roots that are opposite numbers?
Explanation opens after your attempt
Correct Answer
A. \(x^2-16=0\)
Concept
\(x^2-16=0\) gives \(x=\pm4\), which are opposite numbers. Pure quadratics often give opposite roots.
Why this answer is correct
The correct answer is A. \(x^2-16=0\). \(x^2-16=0\) gives \(x=\pm4\), which are opposite numbers. Pure quadratics often give opposite roots.
Exam Tip
\(x^2-16=0\) से \(x=\pm4\) मिलता है, जो विपरीत संख्याएँ हैं। शुद्ध द्विघात में अक्सर विपरीत मूल मिलते हैं।
