Question 833402
Standard form would be {{{f(x)=a(x-h)^2+k}}}, and the vertex is (h,k).  If {{{a>0}}} then vertex is a minimum; if {{{a<0}}}, vertex is a  maximum.


Study the lesson, "Completing the Square to Solve General Quadratic Equation", from the lessons link in my profile.  Completing the Square will allow you to put your function into standard form.
