Which equation gives real, irrational and distinct roots?कौन सा समीकरण वास्तविक, अपरिमेय और भिन्न मूल देता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x^2-10x+23=0)(x^2-10x+23=0)
In the first equation, (D=100-92=8>0), and (8) is not a perfect square. So the roots are real, irrational and distinct.पहले समीकरण में (D=100-92=8>0) है और (8) पूर्ण वर्ग नहीं है। इसलिए मूल वास्तविक, अपरिमेय और भिन्न हैं।
