how about using real math symbols?
f(x) = (2x-2)^2 - 3x^2 + 6
= 4x^2 - 8x + 4 - 3x^2 + 6
= x^2 - 8x + 10
Now you need a perfect square.
= x^2-8x+16 + 10-16
= (x-4)^2 - 6
solve for the vertex
f(X) = (2x-2)squared -3xsquared +6
plss.. solve this for me deadline tomorrow in the afternoon.. need your help ma'am/sir.. thank you. :D
