All you have to do is divide 12 by negative 12.
what do you get.

Answer 3

by finding the square

Answer 4

completing the square

Answer 5

I'm changing the variable to "d" because it confused me.

6x2 = 12d-24
^ Multiply what you can. (6 and 2)
12 = 12d-24
^ Add 24 to both sides so that you can get rid of the 24 on the right side.
36 = 12d
^ Divide 12 from both sides so that you only have "d" left.

3 = d

Hope this helps! (:

Answer 6

completing the square?

Answer 7

yes

Answer 8

3= x

Answer 9

That equation is most likely \[6x^{2} = 12x – 24\] First divide out your 6 to simplify the problem and you get \[6x^{2} = 12x – 24 \rightarrow x^2=2x-4\] then put into your standard \[ax^2+bx+c=0\] and solve

Answer 10

how?

Answer 11

If you are completing the square then you just need to follow the steps outlined in your lecture, if you are solving for x then I would start with factoring.

Answer 12

you cant do the completing the square?
