क्या \(x^2+4=0\) एक द्विघात समीकरण है?

Is \(x^2+4=0\) a quadratic equation?

Explanation opens after your attempt
Correct Answer

A. हाँ क्योंकि \(x^2\) का गुणांक (1) हैYes because the coefficient of \(x^2\) is (1)

Step 1

Concept

In \(x^2+4=0\), the coefficient of \(x^2\) is (1), so it is quadratic. Having real roots is not a condition for being quadratic.

Step 2

Why this answer is correct

The correct answer is A. हाँ क्योंकि \(x^2\) का गुणांक (1) है / Yes because the coefficient of \(x^2\) is (1). In \(x^2+4=0\), the coefficient of \(x^2\) is (1), so it is quadratic. Having real roots is not a condition for being quadratic.

Step 3

Exam Tip

\(x^2+4=0\) में \(x^2\) का गुणांक (1) है इसलिए यह द्विघात है। वास्तविक मूल होना द्विघात होने की शर्त नहीं है।
