Question 981541
1.)
F(x)= 2/x+4 -4
WHAT?



2.)
g(x)= -2x^2 +4x-6
{{{g(x)= -2x^2 +4x-6}}}


Complete The Square.
{{{-2(x^2-2x+3)}}}
{{{-2(x^2-2x+1-1+3)}}}-------See the lesson why 1 is chosen.
{{{-2((x^2-2x+1)-1+3)}}}
{{{-2((x-1)^2+2)}}}
{{{highlight(g(x)=-2(x-1)^2-4)}}}
Solve this for {{{g(x)=0}}} to find the zeros.  You will NOT need to remultiply the square binomial in order to do this; doing so would take you away from the use of Completing The Square that was done.

Read the vertex directly from the standard form equation or function.
Vertex is (1,-4).
