something+ another something =-6
....

Answer 7

Answer 8

What is (-2)(-4) and (-2)+(-4)?

Answer 9

8 and -6... oh I just missed a second negative sign?

Answer 10

Yes! :)
Ok so once you find the two factors of 8 that does the trick
to satisfy:
something*another something=8
something+ another something =-6

Then you plug em into here:
(x+? )(x+?) and you are done

Answer 11

Do you know what to write in the place of those ?'s

Answer 12

(x+(-2))(x+(-4))
or you could write
(x-2)(x-4) :)
