समीकरण \(x^2+4=0\) के वास्तविक मूलों की संख्या कितनी है?
How many real roots does \(x^2+4=0\) have?
Explanation opens after your attempt
Correct Answer
C. (0)
Concept
Because \(x^2\ge 0\) so \(x^2+4\) never becomes (0). Therefore it has no real root.
Why this answer is correct
The correct answer is C. (0). Because \(x^2\ge 0\) so \(x^2+4\) never becomes (0). Therefore it has no real root.
Exam Tip
क्योंकि \(x^2\ge 0\) होता है इसलिए \(x^2+4\) कभी (0) नहीं बनता। इसलिए कोई वास्तविक मूल नहीं है।
