Easy Mathematics Quadratic Equations Class 10 Level 30

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. \(a\neq 0\)

Step 1

Concept

If (a=0), the \(x^2\) term disappears. So \(a\neq 0\) is necessary for a quadratic equation.

Step 2

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.

Step 3

Exam Tip

यदि (a=0) हो जाए तो \(x^2\) पद नहीं बचेगा। इसलिए द्विघात होने के लिए \(a\neq 0\) जरूरी है।
