p² - p - 12
= p² + 3p - 4p - 12
=p(p + 3) - 4(p + 3)
= (p - 4)(p + 3)
= (p + 3)(p - 4)

q² + 3q - 10
= q² + 5q - 2q - 10
= q(q + 5) - 2(q + 5)
= (q + 5)(q - 2)

x² - 11x + 30
= x² - 5x - 6x + 30
= x(x - 5) - 6(x - 5)
= (x - 6)(x - 5)
Jawaban D

y² + y - 20
= y² + 5y - 4y - 20
= y(y + 5) - 4(y + 5)
= (y - 4)(y + 5)
