# EASY Q (Multiplying sign rules)

ASMATHSHELPME
Hi,

I've tottally confused myself over the mutiplying rules.
Can someone please tell me all the rules

+x+ =
-X+ =
+X- =
-X- =

Because I am stupid and keep messing up my polynomials with them.

look forward to posting many easy questions for you guys, Dam some of this stuff is complicated you guys are good.

AS.

Same signs= positive,

Different signs= negative:

+x+= +
-x- = +
+x- = -
-x+ = -
