यदि (p(x)=x-2+4x+1) है, तो इसके शून्यकों का योग और प्रकार क्या है?
If (p(x)=x-2+4x+1), what are the sum and type of its zeroes?

Correct Answer
A. योग (-4), दोनों अपरिमेय वास्तविकSum (-4), both irrational real
Concept
The sum is \(-\frac{b}{a}=-4\) and (D=16-4=12), not a perfect square. Hence both zeroes are irrational real.
Why this answer is correct
The correct answer is A. योग (-4), दोनों अपरिमेय वास्तविक / Sum (-4), both irrational real. The sum is \(-\frac{b}{a}=-4\) and (D=16-4=12), not a perfect square. Hence both zeroes are irrational real.
Exam Tip
योग \(-\frac{b}{a}=-4\) और (D=16-4=12) है, जो पूर्ण वर्ग नहीं है। इसलिए दोनों शून्यक अपरिमेय वास्तविक हैं।
