For this case we have the following expression:
-x (7x + 2) + x ^ 2
Rewriting we have:
(-7x ^ 2 -2x) + x ^ 2
Adding similar terms we have:
-6x ^ 2 - 2x
Answer:
The simplified expression is given by:
-6x ^ 2 - 2x
Answer:
B. -x + 8
Step-by-step explanation:
Given expression

Consider the numerator 
First, use distributive property:

Open the brackets:

Combine the like terms:

Again use distributive property:

Now, the expression is
