द्विघात समीकरण \(ax^2+bx+c=0\) में (a) के लिए आवश्यक शर्त क्या है?
What is the required condition for (a) in \(ax^2+bx+c=0\)?
Explanation opens after your attempt
Correct Answer
C. \(a\neq 0\)
Concept
If (a=0), the \(x^2\) term disappears. So \(a\neq 0\) is necessary for a quadratic equation.
Why this answer is correct
The correct answer is C. \(a\neq 0\). If (a=0), the \(x^2\) term disappears. So \(a\neq 0\) is necessary for a quadratic equation.
Exam Tip
यदि (a=0) हो जाए तो \(x^2\) पद नहीं बचेगा। इसलिए द्विघात होने के लिए \(a\neq 0\) जरूरी है।
