Correct Answer

B. (5)

Step 1

Concept

(2x-4\(x^3-1\)=2x-7-2x-4), and \(2x^7\) cancels. The remaining \(9x^5-2x^4\) has degree (5).

Step 2

Why this answer is correct

The correct answer is B. (5). (2x-4\(x^3-1\)=2x-7-2x-4), and \(2x^7\) cancels. The remaining \(9x^5-2x^4\) has degree (5).

Step 3

Exam Tip

(2x-4\(x^3-1\)=2x-7-2x-4) और \(2x^7\) कटता है। बचा \(9x^5-2x^4\) है जिसकी डिग्री (5) है।
