(4x2-2x)(3x2-2x+1)=
(8-2x)(7-2x)=
56-16x-14x+4x^2= (^2 means squared ;) )
4x^2-30x+56
This means that (x-6)(x+2) = f(x) is the equation for the parabola due to that if you plug these in, when x=6 and x=-2 then y=0. Expanding it, we get
x^2+2x-6x-12=x^2-4x-12. Since the x coordinate of the vertex is -b/2a, it's 4/2=2
