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
Correct Answer

C. दो भिन्न अपरिमेय शून्यकTwo distinct irrational zeroes

Step 1

Concept

The discriminant is (D=36-16=20), and (20) is not a perfect square. So the zeroes are real, distinct, and irrational.

Step 2

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.

Step 3

Exam Tip

विविक्तकर (D=36-16=20) है और (20) पूर्ण वर्ग नहीं है। इसलिए शून्यक वास्तविक भिन्न और अपरिमेय हैं।
