Answer:
The answers A, B, and C all work for this problem. The answer D is the only one that does not.
Step-by-step explanation:
When looking at two parenthesis being multiplied together and being equal to 0, we know that at least one of the parenthesis must be equal to 0 for it to be true. In A and C, the first parenthesis will be equal to 0 due to a = -6.
(a + 6)
(-6 + 6)
(0)
And in B, we can see that the second parenthesis would be equal to 0 due to b = 1
(b - 1)
(1 - 1)
(0)
Now we can try the D options, but will note that they do not work for either parenthesis.
(a + 6)(b - 1)
(0 + 6)(0 - 1)
(6)(-1)
