Question

What is the missing coefficient of the x-term of the poduct (-x-5)^2 after it has been simplified

Answer 1

Answer:

The missing coefficient of the x-term of the given expression $(-x-5)^2=x^2+10x+25$ after simplified is 10

Step-by-step explanation:

Given expression is $(-x-5)^2$

To find the missing coefficient of the x-term of the given expression as below:

First Solve the given expression :

$(-x-5)^2$ which is in the form of $(x-y)^2=x^2-2xy+y^2$

Here x=-x and y=5

$(-x-5)^2=(-x)^2-2(-x)(5)+(5)^2$

$=x^2+10x+25$

Therefore $(-x-5)^2=x^2+10x+25$

The missing coefficient of the x-term of the given expression $(-x-5)^2=x^2+10x+25$ after simplified is 10
