Complete-The-Square for the x.
x%5E2-8x%2B7%2B%288%2F2%29%5E2-%288%2F2%29%5E2
x%5E2-8x%2B7%2B16-16
x%5E2-8x%2B16%2B7-16
%28x-4%29%5E2-9
Vertex would be (4,-9).

Complete the square:



Divide the first-degree term by 2, square the result, and both add and subtract that value from the RHS. -8 divided by 2 is -4, -4 squared is 16, add and subtract 16 from the right-hand side:



Now the first three terms in the RHS are a perfect square, namely , so:



Check the answer:

The vertex of is the point
