How do you factor -108?

Answer 1

115

Answer 2

Apparently you are trying to factor a trinomial, and trying to find two factors of 108 that add up to -7. Unfortunately it doesn't have any. The closest you can get is 6 and -18, which add up to -12.

Go back to the original problem and check it again because something is not quite right. Either the 108 is wrong or the -7 is.

Answer 3

1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

-1, -2, -3, -4, -6, -9, -12, -18, -27, -36, -54, -108

Answer 4

1, 2, 3, 6, 9, 18, 27, 54, -1, -2, -3, -6, -9, -18, -27, -54

1, 3, 7, 21, -1, -3, -7, -21

Answer 5

The same way as 16, just add the negative counterparts. 1, -1, 2, -2, 4, -4, 8, -8, 16, -16
