    a=6 b=-24 c=32. to find vertex, you do -b/2a. so (-)(-24)/2(6) so, it would be 24/12, which is 6. then you have to plug that in to find..i think? lol i'm wrong, sorry

    Yes, to find the x value of the vetex, use -b/2a, but @hiimchristina it's would be 24/12 = 2, not 6 Then plug two in you equation and solve for y, and you'll find the corresponding value of y for that x (2).

    so, it would be 2. then you plug it in 6{2}^2 - 24(2) + 32
