यदि (T(x)=x-3\(x^5-2x^3+1\)-x-8+2x-6+5x), तो (T(x)) की डिग्री क्या है?
If (T(x)=x-3\(x^5-2x^3+1\)-x-8+2x-6+5x), what is the degree of (T(x))?
Explanation opens after your attempt
C. (3)
Concept
On expanding, we get \(x^8-2x^6+x^3-x^8+2x^6+5x\). Higher terms cancel and the degree remains (3).
Why this answer is correct
The correct answer is C. (3). On expanding, we get \(x^8-2x^6+x^3-x^8+2x^6+5x\). Higher terms cancel and the degree remains (3).
Exam Tip
फैलाने पर \(x^8-2x^6+x^3-x^8+2x^6+5x\) मिलता है। बड़े पद कट जाते हैं और डिग्री (3) रहती है।
