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