to find zeros, you need to factor each one and find the value of x that makes the equation zero.
a. (x-6)(x-2)
x = 6, 2
b. (x+6)(x+2)
x= -6, -2
IT'S B.
c. can't be factored
d. can't be factored.
e. can't be factored.

Is that -6 and -2 or 6 and -2
The first means those zeroes mean (x + 6) = 0 or (x + 2) = 0
so (x + 6)(x + 2) = 0 = x^2+8x+12
b)
The second (x - 6)(x + 2) = 0 = x^2-4x + 12 which isn't an option.

I think it is D just by thinking in my head...
Because it has to be either A or D due to the -X
