Is this correct

[vermonstervt]

(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!

-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

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

should be 2(-2+7) ; -(-2) = 2
so answer is +10

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???????


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;

work within the perenthesis firt. remember pemdas???
-2+3= POSSITIVE 1
now,
-2+1=-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.
second you dont talk to me like that.

got it?

WHAT??? you can mess up poeple too. im not the only that makes mistakes.
