Question

what is the coefficient of the first term in this expression?
10n² - m² - 4

Explanation:

Step1: Identify the first term

The expression is \(10n^{2}-m^{2}-4\), so the first term is \(10n^{2}\).

Step2: Determine the coefficient

The coefficient of a term is the numerical factor. For the term \(10n^{2}\), the numerical factor (coefficient) is 10.

Answer:

10
