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.
