Answer:

The center is:
(2, -4)
Step-by-step explanation:
We have the following equation

The general equation of a circle has the following form

Where r is the radius and the point (h, k) is the center of the circle
To transform the given equation in the general equation of a circumference we must use the method of square completions
Step 1

<u>Step 2</u>
<u> </u>Add and subtract
For an equation of the form


<u>Step 3 </u> Factor the expressions within the parentheses

<u>Step 4 Simplify</u>


Finally

The center is:
(2, -4)
Answer:
h = -4
Step-by-step explanation:
I’m not rlly sure if i did it right & i’m sorry if i didn’t. i used the FOIL method
f= first to first
o=outer to outer
i=inner to inner
l= last to last
so it’d be
8b + 6b = 14b (f)
8b+ 8=16b(o)
-7+6b=-1b(i)
-7+8(l)
and then you add like terms so
[14b+16b-1b]+1
= 29b+1
