Correct Answer

C. (2)

Step 1

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).

Step 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).

Step 3

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।
