##### 1 Answer

**Version 1: Where I assume an #x# was accidentally missed on the #+16# term:**

Vertex form of a quadratic is

where the vertex of the parabola is at

(The vertex is at

**Version 2: Where the question was entered correctly (except for the missing #(y=)# which is needed to make it an equation**

which is equivalent to

This can be rearranged as

for a parabola with a vertex at
