I am working with an old exam that we got full soloution I got problem with their characters schedule ( hope you understand what I mean cause I could not find any translate)

I got the same roots as the soloution but in the characters schedule why do they got \(\displaystyle x-3\) and \(\displaystyle (x+1)^2\) should it not be \(\displaystyle x+3\) and \(\displaystyle (x-1)^2\) or I am missing something, that's what I get when I solve it.

edit: the function maybe was not clearly to see in the picture but here it is \(\displaystyle f(x)=e^x(x^3-2x^2-x+4)-5\)

Regards,
