यदि (p(x)=(r-1)x-2+(r+2)x+5) स्थिर बहुपद हो, तो (r) के बारे में सही निष्कर्ष क्या है?
If (p(x)=(r-1)x-2+(r+2)x+5) is a constant polynomial, what is the correct conclusion about (r)?
Explanation opens after your attempt
B. ऐसा कोई (r) नहीं हैNo such (r) exists
Concept
For a constant polynomial, both (r-1=0) and (r+2=0) are required. These cannot hold together.
Why this answer is correct
The correct answer is B. ऐसा कोई (r) नहीं है / No such (r) exists. For a constant polynomial, both (r-1=0) and (r+2=0) are required. These cannot hold together.
Exam Tip
स्थिर बहुपद के लिए (r-1=0) और (r+2=0) दोनों चाहिए। ये दोनों एक साथ संभव नहीं हैं।
