यदि (p(x)=x-4-1), तो (x=1) और (x=-1) के अलावा वास्तविक शून्यकों की संख्या क्या है?
If (p(x)=x-4-1), how many real zeroes are there besides (x=1) and (x=-1)?
Explanation opens after your attempt
A. (0)
Concept
(x-4-1=\(x^2-1\)\(x^2+1\)). Since \(x^2+1\) has no real zeroes, there are (0) extra real zeroes.
Why this answer is correct
The correct answer is A. (0). (x-4-1=\(x^2-1\)\(x^2+1\)). Since \(x^2+1\) has no real zeroes, there are (0) extra real zeroes.
Exam Tip
(x-4-1=\(x^2-1\)\(x^2+1\)) है। \(x^2+1\) के वास्तविक शून्यक नहीं हैं, इसलिए अतिरिक्त वास्तविक शून्यक (0) हैं।
