The expression you've provided is:

$ab + bc - xc$

This expression can be factored. Here's how:

1. Group the terms involving common factors: $ab + (bc - xc)$ Notice that both $bc$ and $-xc$ have a common factor of $c$.

2. Factor out the common factor $c$ from the second group: $ab + c(b - x)$

So, the factored form of the expression is: $ab + c(b - x)$
