What will be the nature of roots of (3x^2-4x-1=0)?समीकरण (3x^2-4x-1=0) के मूलों की प्रकृति क्या होगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Two real irrational and distinct ((D=28))दो वास्तविक अपरिमेय और असमान ((D=28))
Here (D=(-4)^2-4(3)(-1)=28). (28) is positive but not a perfect square, so the roots are irrational and distinct.यहाँ (D=(-4)^2-4(3)(-1)=28) है। (28) धनात्मक है पर पूर्ण वर्ग नहीं है, इसलिए मूल अपरिमेय असमान हैं।
