3 (t + 2) - t (t + 2) = (t + 2) (3 - t)

ab (b - 3) + a² (b - 3) = (b - 3) (ab + a²) = a (b - 3) (b + a)

c (c - d) + d (d - c) = c (c - d) + d (-c + d) = c (c - d) - d (c - d) = (c - d) (c - d)

k (m - 3n) - p (3n - m) = k (m - 3n) - p (-m + 3n) = k (m - 3n) + p (m - 3n) =

= (m - 3n) (k + p)

5 (y + 3) - a (y + 3) - a (y + 3) - x (y + 3) = (y + 3) (5 - a - a - x) =

= (y + 3) (5 - 2a - x)

2 (x - 4) + c (4 - x) - a (x - 4) = 2 (x - 4) + c (-x + 4) - a (x - 4) =

= 2 (x - 4) - c (x - 4) - a (x - 4) = (x - 4) (2 - c - a)
