Reiny Thanks for your help. But you lost me. I still end up with +/- 7 How did you get 1/16 I am con fused here.

Question

no 2 you have to take 1/2 of 3/2 which would be 3/4.
then 3/4 squared is 9/16

so line 4 should read

x^2 - (3/2)x + 9/16 = -1/2 + 9/16
.
.
.
(x-3/4)^2 = 1/16 ( how did you get 1/16)
..

x=1 or x=1/2

9/16- 1/2= 9/16-8/16= 1/16
