किस असमानता का कोई वास्तविक हल नहीं है?
Which inequality has no real solution?
Explanation opens after your attempt
B. \(x^2+4\leq 0\)
Concept
\(x^2+4\) is always at least (4), so \(x^2+4\leq 0\) is impossible. Use the minimum value to judge solutions.
Why this answer is correct
The correct answer is B. \(x^2+4\leq 0\). \(x^2+4\) is always at least (4), so \(x^2+4\leq 0\) is impossible. Use the minimum value to judge solutions.
Exam Tip
\(x^2+4\) हमेशा कम से कम (4) होता है इसलिए \(x^2+4\leq 0\) असंभव है। न्यूनतम मान से हल का अनुमान लगाएं।
