Start with the given expression.


Take half of the coefficient to get . In other words, .


Now square to get . In other words,


Now add and subtract . Make sure to place this after the "x" term. Notice how . So the expression is not changed.


Group the first three terms.


Factor to get .


Combine like terms.


So after completing the square, transforms to . So .


So is equivalent to .


Notice how is in vertex form where the vertex is (h,k)


Since and , this means that the vertex is

Write in vertex form: :
You can convert to the vertex form of the equation by "completing the square"
Set this function equal to zero.
Subtract 1 from both sides.
Add the square of half the x-coefficient to both sides, that's )
Factor the trinomial on the left side.
Add to both sides.
Compare with the standard vertex form:
The vertex is located at (h, k), so, and
The vertex in your equation is located at: (,)
Check the graph of the equation:
