Do you know how to find your A, your B, any your C?
Wait- just re read the question. You're looking to use the quadratic formula, right?
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
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
Is that good or do you want to do the process together?
could we do it together to make sure i'm doing it right?
Alright, to heck with the stupid equation. I'm drawing it
Okay, so lets do the a's first
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
Lets to b next. |dw:1331688080301:dw|
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
Any questions so far?
Okay :) Now lets do c.|dw:1331688316770:dw|
And all of that is equal to x Now we need to solve for x
And that's all there is :)
thank you so much. i think i got it.
You're welcome :) medal?
could you help me again?
