please help my simplify this a^2-2ab+b^2/a-b?

a^2-2ab+b^2/a-b = (a-b)^2 /(a-b ) = a-b

a^2-2ab+b^2 /a-b= (a-b)^2/a-b= a-b
you're good

~sig~
7 days without soccer makes one weak

(a-b)^2/(a-b)=a-b

I don't even know what the operation you are supposed to do is.
I just finished 6th grade.

(a^2 - 2ab + b^2)/(a - b)
= (a^2 - ab - ab + b^2)/(a - b)
= (a - b)(a - b)/(a - b) (cancel out a - b)
= (a - b)/1
= a - b

(a - b)(a - b)
----------------
(a - b)

a - b
