यदि (M(x)=\(x^3-2\)2-\(x^6-4x^3\)+7x-2), तो (M(x)) की डिग्री क्या है?
If (M(x)=\(x^3-2\)2-\(x^6-4x^3\)+7x-2), what is the degree of (M(x))?
Explanation opens after your attempt
C. (2)
Concept
(\(x^3-2\)2=x-6-4x-3+4), and after subtraction the higher variable terms cancel. The remaining \(7x^2+4\) has degree (2).
Why this answer is correct
The correct answer is C. (2). (\(x^3-2\)2=x-6-4x-3+4), and after subtraction the higher variable terms cancel. The remaining \(7x^2+4\) has degree (2).
Exam Tip
(\(x^3-2\)2=x-6-4x-3+4) होता है और घटाने पर चर के बड़े पद कट जाते हैं। बचा \(7x^2+4\) है जिसकी डिग्री (2) है।
