Answer:
D. X= ± square root of 8 - 2
Step-by-step explanation:
Given quadratic equation is \[x^{2}+4x=4\]
Rearranging the terms: \[x^{2}+4x-4=0\]
This is the standard format of quadratic equation of the form \[ax^{2}+bx+c=0\]
Here, a=1 , b=4 and c=-4.
Roots of the quadratic equation are given by \[\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}\]
Substituting the values and calculating the roots:
\[\frac{-4 \pm \sqrt{(-4)^{2}-4*1*(-4))}}{2*1}\]
= \[\frac{-4 \pm \sqrt{32}}{2}\]
= \[\frac{-2*2 \pm 2*\sqrt{8}}{2}\]
= \[-2 \pm \sqrt{8}\]
Hence option D is the correct option.

I can help, but I didn’t see a question posted. I’m not sure if you tried to post a picture or something, but I don’t see a question.
You complete the square
Vertex form is
so break it into parts
to keep the equation in balance to add and subtract the same value
so value ?? is
then factor the perfect square
Answer:
The total number of customers for the two days is 16x + 8
Step-by-step explanation:
Number of customers on Monday = 10x - 8
Number of customers on Tuesday = 6x + 16
Total numbers of customers for the two days = 10x - 8 + 6x + 16
Total numbers of customers for the two days = 16x + 8
