Bay 12 Games Forum

My old Steam account was permanently hijacked by my cousin.
Why do you think my steam ID is toony246811?
My first one was toony246810.

I re-bought all my games, heh.

Vector, get a steam account, there's like a whole bunch of people you can talk to in REAL TIME, including me.

It's totally free accept that we have to invite you because you don't own any games, but just put your future STEAM ID on the forums and presto, instant IRC chat.

I think it's a good idea actually.

I'm not spoiling, but he gets his just desert in something spectacular.

Mmmmmm anime hud pictures.

Keep going it'll be good.

I have anxiety as well, I just deal with it though, heh.

It gets less worse as you keep going.  I've never really had a solution to it besides just keep moving forward.

I've been in every Vote Mafia right?

Guess I'll have to be IN this.

Funny that, I did factorizing a little earlier in Math, I like just learned this junk.  Mehhhh.
I'll just do some examples,
x²-4
Now you just break it down,
(x+2) (x-2)
There you go!
Now when you foil it you get x time x making x².
When you times x and 2, x and -2 you get 2x and -2x which cancel themselves out.
Lastly, you do 2 time -2 which would be -4!


Let's do a harder one,
x²-2x-8
Now break it down,
(x+2) (x-4)
I did this like the last time, only we have the consider the number in the middle.
First you do x times x to get x[sup2[/sup].
Then you time x and 2, x and -4 to make 2x and -4x.  You add these to make -2x for the sum.
Lastly you time 2 and -4 to make -8.


Let me explain something.

x²+2x+1
x²+1x-12
x²-2x+1
x²-1x-12

Here are the four different types of questions for this you'll come across.
There are going to be ones like this too,
16x²+4x+4
But I don't really know how to do these.

Anyway, when you have a question that looks like this,
x²+2x+1
With two pluses, that means the factoring answers will BOTH be pluses as well.
(x+1) (x+1)

When you have a question like this,
x²+1x-12
With the first being a plus and the last being a minus, that will make the answer one plus and one minus.
(x+4) (x-3)

Now,
x²-2x+1
When the first symbol is minus and second is plus, that means BOTH factors will be minus.
(x-1) (x-1)
See?

Lastly, we have,
x²-1x-12
Where both symbols are minus.  That means one factor is going to be minus and the other plus.
(x-4) (x+3)

Let's do a quick over view,
    Q            A
+ and + = + and +
+ and - = + and -
- and + = - and -
- and - = - and +


Now here's a question for you,
What would the answer be to,
x²-6x+9?

EDIT:
Seems I'm too late to help, heh.
