Correct Answer

B. (5)

Step 1

Concept

(3x-5\(x^2-1\)=3x-7-3x-5), and \(3x^7\) cancels. The remaining \(-3x^5+8x^4\) has degree (5).

Step 2

Why this answer is correct

The correct answer is B. (5). (3x-5\(x^2-1\)=3x-7-3x-5), and \(3x^7\) cancels. The remaining \(-3x^5+8x^4\) has degree (5).

Step 3

Exam Tip

(3x-5\(x^2-1\)=3x-7-3x-5) और \(3x^7\) कटता है। बचा \(-3x^5+8x^4\) है जिसकी डिग्री (5) है।
