यदि \(x^2+5x+k=0\) के दो भिन्न वास्तविक मूल हैं, तो (k) के लिए सही शर्त क्या है?
If \(x^2+5x+k=0\) has two distinct real roots, what is the correct condition for (k)?
Explanation opens after your attempt
A. \(k<\frac{25}{4}\)
Concept
For two distinct real roots, (D>0), so (25-4k>0) gives \(k<\frac{25}{4}\). In exams, keep the inequality sign correct while solving.
Why this answer is correct
The correct answer is A. \(k<\frac{25}{4}\). For two distinct real roots, (D>0), so (25-4k>0) gives \(k<\frac{25}{4}\). In exams, keep the inequality sign correct while solving.
Exam Tip
दो भिन्न वास्तविक मूलों के लिए (D>0), इसलिए (25-4k>0) से \(k<\frac{25}{4}\)। परीक्षा में असमानता हल करते समय चिन्ह सही रखें।
