# What is the missing coefficient of the x-term of the product (-x - 5)^{2} after it has been simplified?

**Solution:**

Given, (-x - 5)^{2}

We have to find the missing coefficient of the x term of the given product.

We know, \((a-b)^{2}= a^{2}-2ab+b^{2}\)

So, (-x - 5)^{2} = (-x)^{2} - 2(-x)(5) + (-5)^{2}

= x^{2} - 2(-5x) + 25

= x^{2} + 10x + 25

Therefore, the missing coefficient of the x-term is 10.

## What is the missing coefficient of the x-term of the product (-x - 5)^{2} after it has been simplified?

**Summary:**

The missing coefficient of the x-term of the product (-x - 5)^{2} after it has been simplified is 10.
