The problem:

**(Solving polynomial equations by factoring)**

7. The solutions of x2 - 2x – 24 = 24 are:

A. 6,-4

B. 8, -6

C. 2, 48

D. 20, 30

E. 0,2

I worked that out to

x2 - 2x – 48

and then since

-8 x 6 = -48

and

-8 + 6 = -2

I figure the factors are

(x-8)(x+6)

so the answer is

-8, 6

...right? **no!**

BUT that's not a given choice... only 8, -6. Am I missing something simple that switches the signs, or should did the test writer screw up? I have absolutely no idea where I went wrong... it seems pretty simple.

Help?
