here is the equation:

step 1 - factor .5 out of the first two terms like this:

The blanks are waiting for numbers as you complete the square.
step 2 - take 1/2 of the middle term and put that answer in the first blank. LIke this:

step 3 - multiply 36 by 1/2 to get 18. put this in the second blank. Notice the sign.

step 4 - rewrite the first (_) as a quantity squared and simplify that last 2 numbers as

This is in vertex form.
The vertex is (-6, -8)
Y-intercept is when x = 0.
(0,10)
