1) ac - ad + c cd - bc + bd = a * (c - d) + c * (c - d) b * (c - d) = (c - d) * (a + c -b).

2) mx + my - nx - ny + n m = x * (m - n) + y * (m - n) 1 * (m - n) = (m n) * (x + y - 1).

3) am + cm an + an cn + cn = m * (a + c) n * (a + c) + n * (a + c) = (a + c) * (m - n + n).

4) xy - ny mx + mn + mx - mn = y * (x - n) m * (x - n) + m * (x - n) = (x - n) * (y - m + m).

5) ab + a + ab + b + 2ab + 2 = a * (ab + 1) + b * (ab + 1) + 2 * (ab + 1) = (ab + 1) * (a + b + 2).

6) x xy + x - xy + y - y = x * (x y) 1 * (x y) y * (x y) = (x y) * (x 1 - y).
