Correct Answer

B. (9)

Step 1

Concept

(7x-9\(x^2-1\)=7x^{11}-7x-9), and \(7x^{11}\) cancels. The remaining highest power is (9).

Step 2

Why this answer is correct

The correct answer is B. (9). (7x-9\(x^2-1\)=7x^{11}-7x-9), and \(7x^{11}\) cancels. The remaining highest power is (9).

Step 3

Exam Tip

(7x-9\(x^2-1\)=7x^{11}-7x-9) और \(7x^{11}\) कटता है। बची सबसे बड़ी घात (9) है।
