1. Factoriza:
 (x – 2)y – (x – 2)z
 x(x + 5) + y(x + 5) – z(x + 5)
 x4(2a – 5b) + x(2a – 5b) – (2a – 5b)
 a(p + q) + b(p + q) + c(p + q)
 mx + m2 + xy + my
 ax + x2 + ab + bx
 ax + bx + cx + ay + by + cy

2. Factoriza:
 m2 – mn + mp – np
 m3 + m2 + m + 1
 m2 + mn + mp + np
 – m – n + x(m +n)
 x(3a – 2b) – 3a + 2b
 (c + 1)(ab + 1) + (a + b)(c + 1)
 3b(2x + 3) + 2x + 3

3. Factoriza:
 x2 + y2 – 5y(x2 + y2)
 1 – x – 2y(1 – x)
 x3 – x2 + x – 1
 5y5 – 15y2z + y3 – 3z
 a5 – a4 + a – 1
 3xy – 3xz + 3x – y + z – 1
 2a2x + 2ax + 2x – a2 – a – 1
