1. (p - 12) (p + 1)

2. (z - 4) (z - 1)

Step-by-step explanation:

$p^{2} - 11p - 12$

$p(\frac{p^{2} }{p} - \frac{2^{2} * 3p }{p} ) + (p - 12)$

p(p - (4 * 3) ) + (p - 12)

p(p - 12) + (p - 12)

$(p - 12) (\frac{p(p - 12)}{p - 12} + \frac{p - 12}{p - 12} )$

(p - 12) (p + 1)

$z^{2} - 5z + 4$

$z^{2} - 4z - z + 4$

$z(\frac{z^{2} }{z} - \frac{2^{2} * z }{z} ) + (-z + 4)$

z(z - 4) + (-z + 4)

$(z - 4) (\frac{z(z - 4)}{z - 4} + \frac{-z + 4}{z - 4} )$

(z - 4) (z - 1)
