How come for the top example the 5 is included in the brackets but for the bottom example it isn't?

If 5 was in the bracket in the second one and you expanded it out, you wouldn't get the original expression

#

If you like all of it in the bracket you can do -2(x^2 -6x - 5/2) and complete the square like that and you'll still get the same answer, but here you can see if you expanded it out, you'd get the original expression
