Factoring: x3-3x2+x-3
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: x-3
Group 2: x3-3x2
Pull out from each group separately :
Group 1: (x-3) • (1)
Group 2: (x-3) • (x2)
-------------------
Add up the two groups :
(x-3) • (x2+1)
Which is the desired factorization

Answer:
= X^3-3X^2+X-3
= X^2(X-3)+1(X-3)
= (X-3) (X^2+1)
