- what is the question ? -
**Damon**, Thursday, August 7, 2014 at 3:29pmYou want zeros of y or what?

if zeros:

4 x^2 - 12 x + 9 = 0

(2 x-3)(2x-3) = 0

x = 1.5, 1.5 double root

If vertex etc:

4 x^2 -12 x = y - 9

x^2 - 3 y = (1/4)(y-9)

x^2 - 3 y + 9/4 = (1/4)y

(x-1.5)^2 = y/4

vertex at (1.5 , 0) which we knew already
