I am trying to align (-(a-1)^2-1)x+(-(a-1)^2-1) and (-(a-1)^2-1)x+1 using phantom command. Since (-(a-1)^2-1)x+1 is missing the (-(a-1)^2-1) part, I added phantom(-(a-1)^2-1), but there is an extra space that I am not sure from were it comes:

I guess it comes from adding the "1", but I do not know how to compensate this extra space.

MWE:

begindocument

[beginarrayc
 (-(a-1)^2-1)x+(-(a-1)^2-1)\
 (-(a-1)^2-1)x+phantom(-(a-1)^2-1)1
endarray]

enddocument

I want this output:

You have to remove the 1 from the phantom, since it shows up explicitly outside the phantom. I replace it with placeholder.

[beginarrayc
 (-(a-1)^2-1)x+(-(a-1)^2-1)\
 (-(a-1)^2-1)x+phantom(-(a-1)^2-)1

In response to a comment from the OP, I leave this also, to show what can be done when the phantom and residual term do not share common digits.
