1.vertex form is 
to get into vertex form, complete the square

step 1: group x terms

step 2: factor coefient in front of x^2 term

prep for next step: take 1/2 of linear (1st dgree term) and square it
, 
step 3: add positive and negative of that previous number inside the parenthasees

factor perfect squaer trionmial

take out that -36 by expansion


2. factor out the 2

what 2 numbers multiply to get 12 and add to get 8?
2 and 6

3.
for 

in our case

a=1, b=-7, c=-6


so
and 
4. remember that
so 
treat
as a variable

The choices are (3, 2) (2, 5) (6, 7) and (7, 5). The distance formula given two points is d = square root of [<span>(y2−y1)^2+(x2−x1)^2]. In this case, we try every point in the choices and substitute y1 equal to 6 and x1 equal to 6 as well. The answer is A from the choices.
</span>d=square root of [(6−2)^2+(6−3)2]
d=square root of [(4)^2+(3)^2]
d=square root of [16+9]
d=<span>square root of [</span>25]
d=5
I think it might be x + b square
Answer:
Option B has infinitely many solutions.
