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

= x² - 2(-5x) + 25

= x² + 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.
