    There is no factor common to the who equation but you can factor into two terms

    $\displaystyle a(c-1) - 3(1-x)$

    If you meant $\displaystyle \displaystyle ac - 3 + 3c - a$

    $\displaystyle \displaystyle = ac - a + 3c - 3$

    $\displaystyle \displaystyle = a(c - 1) + 3(c - 1)$

    $\displaystyle \displaystyle = (c-1)(a+3)$.
