Question

I need a refresher. If you have 6(x-1) you get 6x and then do you multiply 6 (-1) and what are the rules again is it -6 or +6?

Answer 1

6 times -1 is -6
if we have a negative times a positive, then it is negative
if we have a positive times a positive or negative times a negative, then it becomes positive

Answer 2

+*+=+
-*+=-
-*-=+

Answer 3

and yes, that would be the correct step -- multiplying 6 and -1 together
just wanted to make sure that was clear
we're using distributive property, so we multiply the outer number by each term inside the parentheses.

Answer 4

Thank you!!! what about a + times a -?

Answer 5

a positive times a negative results in a negative
ie. -1*6 = -6, -2 * 2 = -4, -x * 3 = -3x

Answer 6

it would still be negative, because you are multiplying and it does not change

Answer 7

Ok. :)

Answer 8

positive times a negative and negative times a positive are the same from multiplication properties

a*b = b*a (commutative)
