यदि (p(x)=x-2-6x+4) है, तो उसके शून्यकों की प्रकृति क्या है?
If (p(x)=x-2-6x+4), what is the nature of its zeroes?
Explanation opens after your attempt
C. दो भिन्न अपरिमेय शून्यकTwo distinct irrational zeroes
Concept
The discriminant is (D=36-16=20), and (20) is not a perfect square. So the zeroes are real, distinct, and irrational.
Why this answer is correct
The correct answer is C. दो भिन्न अपरिमेय शून्यक / Two distinct irrational zeroes. The discriminant is (D=36-16=20), and (20) is not a perfect square. So the zeroes are real, distinct, and irrational.
Exam Tip
विविक्तकर (D=36-16=20) है और (20) पूर्ण वर्ग नहीं है। इसलिए शून्यक वास्तविक भिन्न और अपरिमेय हैं।
