Is this correct

What is the sign on the product of two negatives?

Eliz.
 
sign on the product of two negatives is positive

the sign on the product of two negatives is a positive and thanks
 
Have a closer look at what you have substituted inside the brackets. Then do the multiplication by -2 again.
 
are these correct

(x-y)(y-x) if x=-2 y=3
(-2-3)(3-2)
(-5)(1)=-5
----------------------
(x-y)-(x-y) if x=-2 y=3
(-2-3)-(-2-3)
-5+5=0
------------------------
(-x)+(-y) if x=-2 y=3
(-2)+(-3)=5
----------------------
-xa(x-a) if a =-2 x=4
-4(-2)(-2-4)
8*6=48
and thanks for the help I appreciate it
 
G'day, Benita!

If I number each...

1) Be careful, you made the same mistake as I mentioned before.

2) Good (you can go straight to zero in the future: a - a = 0; (a+b) - (a+b) = 0)

3) You left out a negative sign again (look to the left). Be careful!

4) You might want to check the bracket on the right.

Good luck!
 
are these correct

-a(a-b) if a=-2 b=-7
-2(-2+7)
-2(5)=-10
---------------
(a-x)(-x) if a=2 x=-5
2+5(-5)
7(-5)=-35

(x-y)-(y-x) if x=-2 y=-4
(-2+4)+(4-2)
2+2=4
 
Dennis,
ive seen ALOT of the answers u give out to people. ive analyzed u. and guess wat???

YOU DON'T GET ALOT OF THE STUFF RIGHT.

x(x-y) Where
x=-2
and
y=-3

so the problem to solve would be,

-2(-2--3)

2 negatives equal a possitive.

So that would change the problem into:

-2(-2+3)

work within the perenthesis firt. remember pemdas???
-2+3= POSSITIVE 1



now,
-2+1=-1

OKOKOKOKOKOKOK???????


:!: :?: :idea: :arrow: ANSWER= -1

Actually Denis (not "Dennis") helps a lot of people, which is more than can be said for your spamming of these forums.

you're ok up to here;

-2+3= POSSITIVE 1

NO. It's -2 times 1, which equals -2 : answer is -2
-2(1) means MULTIPLY

Now go away, you little brat; quit disturbing the site and confusing
the people who are asking for help...
 
firt of all im not a brat.
