यदि (R(x)=\(x^4+2x^2\)2-x-8-4x-6+5x), तो (R(x)) की डिग्री क्या है?
If (R(x)=\(x^4+2x^2\)2-x-8-4x-6+5x), what is the degree of (R(x))?
Explanation opens after your attempt
C. (4)
Concept
(\(x^4+2x^2\)2=x-8+4x-6+4x-4). After higher terms cancel, \(4x^4+5x\) remains, whose degree is (4).
Why this answer is correct
The correct answer is C. (4). (\(x^4+2x^2\)2=x-8+4x-6+4x-4). After higher terms cancel, \(4x^4+5x\) remains, whose degree is (4).
Exam Tip
(\(x^4+2x^2\)2=x-8+4x-6+4x-4) होता है। बड़े पद कटने के बाद \(4x^4+5x\) बचता है जिसकी डिग्री (4) है।
