समीकरण \(4x^2-5x-2=0\) के मूलों की प्रकृति क्या होगी?
What will be the nature of roots of \(4x^2-5x-2=0\)?
Explanation opens after your attempt
A. दो वास्तविक अपरिमेय और असमान ((D=57))Two real irrational and distinct ((D=57))
Concept
Here (D=(-5)2-4(4)(-2)=57). (57) is positive but not a perfect square, so the roots are irrational and distinct.
Why this answer is correct
The correct answer is A. दो वास्तविक अपरिमेय और असमान ((D=57)) / Two real irrational and distinct ((D=57)). Here (D=(-5)2-4(4)(-2)=57). (57) is positive but not a perfect square, so the roots are irrational and distinct.
Exam Tip
यहाँ (D=(-5)2-4(4)(-2)=57) है। (57) धनात्मक है पर पूर्ण वर्ग नहीं है, इसलिए मूल अपरिमेय असमान हैं।
