Answer 2

B, D

Explanation:

The Zero Product Property simply states that if ab=0 , then either a=0 or b=0 (or both).

The first equation which can be solved by using the zero product property is

`-(x-1)(x+9)=0\\ \\x-1=0\ \text{or}\ x+9=0\\ \\x=1\ \text{or }x=-9`

The second equation which can be solved by using the zero product property is

`3x^2-6x=0\\ \\3x(x-2)=0\\ \\x=0\ \text{or }x-2=0\\ \\x=0\text{ or }x=2`
