Completing the square?

Answer 1

Can someone tell me if I did anything wrong and how to finish it?

Answer 2

start from step 3 ?
since the leading coefficient is not equal to 1, factor out 4 first and then complete the square :=))

Answer 3

actually 2nd step \[\huge\rm 4x^2-8x=5\]
\[\huge\rm 4(x^2-2x)=5\]
now complete the square
and don't forget to multiply the common factor 4 by (b/2)^2 :=))
