Limite non chiaro

Salve a tutti, vorrei chiedervi un parere sulla risoluzione del seguente limite:

[tex]\displaystyle\lim_{x \to +\infty}\frac{(x+1)\sqrt{x^2-2x}-x^2+x}{x-1}[/tex]

Ho provato ad isolare i termini asintoticamente di ordine maggiori ma mi rimane comunque una forma indeterminata, intuisco che un [tex]x^2[/tex] da una parte dovrà andare via con un altro [tex]x^2[/tex] dall'altra e si giocherà tutto sul primo ordine. Però boh...forse Hopital? però non si presenta come un infinito/infinito.

la puoi risolvere in almeno 2 modi: o con gli sviluppini o razionalizzando per eliminare la radice

allego qui gli svolgimenti
