Math Testing? Lol.
 
Math tutoring with Nightmare n___n

Wasn't sure where else to post this, but here goes!

Alright.
Can I see some of the problems your doing ?
So I can see if I've even done it. xD

Ginger 03-18-2011 07:22 PM

All of it is Factoring.

These two are zero-product property.
(x+5)(x-0)=0

(2x+1) squared

(Sorry, my boyfriend just walked into the room and I got distracted >.<)

Nightmare 03-18-2011 07:58 PM

FACTORING. *A*
I LOVE factoring. >u<

The first one I haven't done before. ono
(2x+1)² ... do you just need helping solving it ?
I can do that.

Ginger 03-18-2011 09:25 PM

Yes I need the steps on how to solve it and possibly an answer to one of those so I can possibly figure out how to do the other one. There is an =0 at the end of the second one as well.

Well, solving for x on the second one is easy.

2x + 1 = 0
* the reason why there is only one equation is because x is the same for both, seeing as 2x+1 is squared.
Subtract one. 2x = -1
Divide by two. x = -1/2

The other one would be done similarly.
Set both equal to zero.
x+5=0 and x-0=0
You'd subtract five for the first one and add zero on the second
to get x=-5 and x=0.

Holy moly thank you! That explains a lot. My math teacher gets distracted and goes off topic all the time, so it is difficult to understand the steps.

Nightmare 03-20-2011 09:29 PM

I hate teachers that do that. D<
But I can understand.
Sometimes when my teacher starts doing that,
I almost go teach the class. xD

Anything else you need help on ? 8D
It looks like your doing Algebra stuff. ouo
