I can't figure this problem out for the life of me. I understand the follow up problems, but can't figure out the two main problems. I'm hoping that someone can help me out here:
A. Show that the vertex form expression -2(x-125)^2 + 31,250 is equivalent to 500x-2x^2
and
B. X= the width of a rectangle with a perimeter 200, and find an expression for the area in terms of x
(second half)
Show that your expression in part a is equivalent to -(x-50)^2 + 2500
I would apprechiate any help someone can give on this. Thanks!
