यदि (\(n^2-16\)x-2-3x+7=0) द्विघात समीकरण है, तो (n) पर सही शर्त क्या है?
If (\(n^2-16\)x-2-3x+7=0) is a quadratic equation, what is the correct condition on (n)?
Explanation opens after your attempt
C. \(n\neq \pm4\)
Concept
For the equation to be quadratic, \(n^2-16\neq0\) is needed. Hence both \(n\neq4\) and \(n\neq-4\) are necessary.
Why this answer is correct
The correct answer is C. \(n\neq \pm4\). For the equation to be quadratic, \(n^2-16\neq0\) is needed. Hence both \(n\neq4\) and \(n\neq-4\) are necessary.
Exam Tip
द्विघात होने के लिए \(n^2-16\neq0\) होना चाहिए। इसलिए \(n\neq4\) और \(n\neq-4\) दोनों जरूरी हैं।
