What is the value of x?

(1) (x + 2)(x + 3) = 0

(2) x^2 + 5x + 6 = 0

I answered that both are sufficient alone...
Statement one tells me that X is -2 and -3
and I can do the same for statement two...why is this not the OA?

You said it yourself mate but u forgot to put an "or" where and is in your calculation. x is unique, we want to find a unique value of x. Both the statements are similar and give the same information. x can either be -2 or -3. It cannot be both and since we cannot decide a unique value for x, even combined, both of them are insufficient. Hence E.

When the question asks, "What is the value of x?", it is imperative to find ONE AND ONLY ONE value for x.

Statement 1:
x = -2 or x = -3. This gives us two values for x. NOT SUFFICIENT.

Statement 2:
Can be written as (x + 2) (x + 3) = 0
This is the same as statement 1 and for exactly the same reason as above, NOT SUFFICIENT.

Combining the two statements, we still have two possible values for x. thus NOT SUFFICIENT.

Both give -2 and -3 but we are not sure about the the value of X so the answer is E

1. Gives x = -2,-3
2. Same

Both statements same, so can't decide a value for x. E
