Hi guys basically I'm trying to solve the following equation by completing the square...

x^{2}-3x-5=0

However, when I try and form the square and complete it I seem to run into trouble

(x-1.5)(x-1.5)=x^{2}-3x+2.25

(x-1.5)^{2}-7.25=0

(x-1.5)^{2}=7.25

x-1.5= (root 29) divided by 2

Then I get kinda stuck. Is this right so far? Can someone please guide me through what to do? Thanks very much for any help.
