We need to divide the next polynomial x^3+x^2−2x+3 by x-1.
First, we need to find an expression to cancel the firs term:
(x-1)*(x^2)= x^3 - x^2
Subtract :

Find another expression to cancel the new first term:
(x-1)*(2x)=2x^2-2x
Subtract :

Hence, the whole answer is given by the terms that we found(quotients) plus the remainder over the dividend.
