Correct Answer

A. \(5x^2-9\)

Step 1

Concept

\(5x^2-9\) has degree (2), and the (x) term is absent. So the coefficient of (x) is (0).

Step 2

Why this answer is correct

The correct answer is A. \(5x^2-9\). \(5x^2-9\) has degree (2), and the (x) term is absent. So the coefficient of (x) is (0).

Step 3
