यदि (D=-(b+3)2) और \(b\neq-3\), तो मूलों की प्रकृति क्या होगी?

If (D=-(b+3)2) and \(b\neq-3\), what will be the nature of roots?

Explanation opens after your attempt
Correct Answer

A. वास्तविक मूल नहींNo real roots

Step 1

Concept

When \(b\neq-3\), ((b+3)2>0) and (D<0). So there will be no real roots.

Step 2

Why this answer is correct

The correct answer is A. वास्तविक मूल नहीं / No real roots. When \(b\neq-3\), ((b+3)2>0) and (D<0). So there will be no real roots.

Step 3

Exam Tip

जब \(b\neq-3\), तब ((b+3)2>0) और (D<0) होगा। इसलिए वास्तविक मूल नहीं होंगे।
