Question

What is the vertex of 3x^2-6x+2

Answer 1

\[
3 x^2 - 6 x +2= 3( x^2 -2 x) +2=3(x^2 -2 x +1 -1)+2
\]
Can you finish it now?

Answer 2

a=3, b=-6, the x coordinate of the vertex =-b/2a = 6/6 =1
vertex is located at (1,y) To get y just substitute the value of 1 for x in your original formula.

Answer 3

From a casual inspection it appears that it is at point (1,-1)
