यदि (p(x)=mx+n) और (p(1)=p(2)), तो (p(x)) रेखीय कब हो सकता है?
If (p(x)=mx+n) and (p(1)=p(2)), when can (p(x)) be linear?
Explanation opens after your attempt
C. कभी नहींNever
Concept
From (p(1)=p(2)), (m+n=2m+n), so (m=0). At (m=0), the polynomial is not linear.
Why this answer is correct
The correct answer is C. कभी नहीं / Never. From (p(1)=p(2)), (m+n=2m+n), so (m=0). At (m=0), the polynomial is not linear.
Exam Tip
(p(1)=p(2)) से (m+n=2m+n) और (m=0) मिलता है। (m=0) पर बहुपद रेखीय नहीं रहता।
