Explanation opens after your attempt
A. दो भिन्न अपरिमेय वास्तविक शून्यकTwo distinct irrational real zeroes
Concept
(D=36-28=8). It is positive but not a perfect square, so the zeroes are real and irrational.
Why this answer is correct
The correct answer is A. दो भिन्न अपरिमेय वास्तविक शून्यक / Two distinct irrational real zeroes. (D=36-28=8). It is positive but not a perfect square, so the zeroes are real and irrational.
Exam Tip
(D=36-28=8) है। (8) धनात्मक है पर पूर्ण वर्ग नहीं, इसलिए शून्यक वास्तविक और अपरिमेय हैं।
