#(x-sqrt5)#

Factored form means that

#(x# #+-#something#) = 0#.

Let's say the equation was:
#x - 3 = 0#

To solve for #x#, we would add #3# to both sides of the equation and get #x = 3#.

As you can see, in the factored form has #-3# while when we solve for #x# we get #3#.

Same case here.
We have #sqrt5#, so it becomes #(x-sqrt5)#.

Hope this helps!
