यदि (L(x)=\(x^6+2x^3\)2-x^{12}-4x-9+7x-5), तो (L(x)) की डिग्री क्या है?
If (L(x)=\(x^6+2x^3\)2-x^{12}-4x-9+7x-5), what is the degree of (L(x))?
Explanation opens after your attempt
C. (6)
Concept
(\(x^6+2x^3\)2=x^{12}+4x-9+4x-6). After higher terms cancel, \(4x^6+7x^5\) remains, whose degree is (6).
Why this answer is correct
The correct answer is C. (6). (\(x^6+2x^3\)2=x^{12}+4x-9+4x-6). After higher terms cancel, \(4x^6+7x^5\) remains, whose degree is (6).
Exam Tip
(\(x^6+2x^3\)2=x^{12}+4x-9+4x-6) होता है। बड़े पद कटने के बाद \(4x^6+7x^5\) बचता है जिसकी डिग्री (6) है।
