व्यंजक (\(w^2-1\)x-4+(w-1)x-2+6) नियतांक बहुपद कब बनेगा?
When will (\(w^2-1\)x-4+(w-1)x-2+6) become a constant polynomial?
Explanation opens after your attempt
A. जब (w=1)When (w=1)
Concept
To become constant, both \(w^2-1=0\) and (w-1=0) are needed. Both conditions are satisfied together at (w=1).
Why this answer is correct
The correct answer is A. जब (w=1) / When (w=1). To become constant, both \(w^2-1=0\) and (w-1=0) are needed. Both conditions are satisfied together at (w=1).
Exam Tip
नियतांक बनने के लिए \(w^2-1=0\) और (w-1=0) दोनों चाहिए। दोनों शर्तें साथ में (w=1) पर पूरी होती हैं।
