Do you know how to find your A, your B, any your C?

- Tia_Sweetheart17

yeah

- anonymous

Wait- just re read the question. You're looking to use the quadratic formula, right?

yes

Okay, good. So your a is 1, your b is 2, and your c is -24
so wherever you see an a in the formula, you put a 1, 2 for the b, and -24 for the c

- anonymous

So, the formula starts with (-b)^2. For that b, you'd put in 2. Do the same with the rest of the a's,b's, and c's and then just solve for x

- anonymous

Is that good or do you want to do the process together?

- Tia_Sweetheart17

could we do it together to make sure i'm doing it right?

- anonymous

sure!

Alright, to heck with the stupid equation. I'm drawing it

Okay, so lets do the a's first

- anonymous

Since your a is 1, that's really simple because it only ever needs to get multiplied by the 2, and 2*1=1. So for a, you don't need to make any changes

- anonymous

Lets to b next. |dw:1331688080301:dw|

- anonymous

Sorry about that extra a; I forgot to mention it when we did a but it's the same situation. Because a is 1 and it's being multiplied, it makes no difference

- anonymous

Any questions so far?

- Tia_Sweetheart17

no

- anonymous

Okay :) Now lets do c.|dw:1331688316770:dw|

- anonymous

And all of that is equal to x
Now we need to solve for x
