The formula for the x-value of the vertex is:
when the form of the equation is:
So, in this case:
----------------
-------------------
Plug this back into the equation to get
The vertex is at:
( 10/3, -100/3 )
---------------------------------
check answer:
Here's the plot:

vertex x part is ====
Y part is
= at =
= at =
= at =
= at =
= at =
Vertex is = and =
the Point (10/3,-100/3) is the vertex of the function
=
.
