Vocaloid
  • Vocaloid
both sides of the equation...
Vocaloid
  • Vocaloid
you have the left side of the equal sign, which is the n(-2n-2)/3 part and the right side, which is the 12 now multiply both sides by 3
carlyleukhardt
  • carlyleukhardt
12=36. But how do i do the first one?
Vocaloid
  • Vocaloid
when you multiply the expression by 3, the 3 in the denominator cancels out

Vocaloid

|dw:1447431754272:dw|
Vocaloid
  • Vocaloid
now we set that equal to 36 and solve for n
Vocaloid
  • Vocaloid
|dw:1447431791768:dw|
Vocaloid
  • Vocaloid
next, distribute the n on the left side
carlyleukhardt
  • carlyleukhardt
Im stuck..!! everything made sense but i don't get the (-2n-2) part.
Vocaloid
  • Vocaloid
apply the distributive property A(B-C) = A*B - A*C n(-2n-2) = ?
carlyleukhardt
  • carlyleukhardt
n=0 ????
Vocaloid
  • Vocaloid
no, I'm not asking you to solve for n, I'm asking you to rewrite the expression
Vocaloid
  • Vocaloid
n*(-2n) = ?
carlyleukhardt
  • carlyleukhardt
-2n= n?????????????????? omg :o IM SO CONFUSED ON WHAT TO DO HERE!!!!
Vocaloid
  • Vocaloid
just multiply them together...
anonymous
  • anonymous
I may be doing my math wrong, but wouldn't it equal -2n^2?
carlyleukhardt
  • carlyleukhardt
I don't know what n is though? So how could i multiply n and that?
Vocaloid
  • Vocaloid
we can still multiply n by n to get n^2, like duck said
Vocaloid
  • Vocaloid
(n)*(-2n) = -2n^2
carlyleukhardt
  • carlyleukhardt
Ohhhh so it equals -2n^2?
Vocaloid
  • Vocaloid
we can perform math operations on variables without knowing what the variables are like, how x + x = 2x
Vocaloid
  • Vocaloid
yes, (n)*(-2n) = -2n^2 now multiply (-2) and n
carlyleukhardt
  • carlyleukhardt
-2*n= n? >_<
Vocaloid
  • Vocaloid
-2*n is just -2n
carlyleukhardt
  • carlyleukhardt
Ohhh. Okay... So that's all?
Vocaloid
  • Vocaloid
now we keep going n(-2n-2) = -2n^2-2n after we apply the distributive property
Vocaloid
  • Vocaloid
|dw:1447432448432:dw|
Vocaloid
  • Vocaloid
then divide both sides by 2
carlyleukhardt
  • carlyleukhardt
36 divided by 2 = 18. So what is the next one i divide?
Vocaloid
  • Vocaloid
don't forget the left side
carlyleukhardt
  • carlyleukhardt
2n?
anonymous
  • anonymous
Just a suggestion... wouldn't you want to square root both sides before dividing?
Vocaloid
  • Vocaloid
why would I take the square root?
anonymous
  • anonymous
Isolation of the variable n, when you have 2n^2, It'd be easier to square root it in the beginning, while you still have a perfect square..

I may be wrong, but that's just how I saw that.
anonymous
  • anonymous
Oh yeah, sorry. I forgot we still had -2n in there.

WOULD SOMEONE JUST HELP WITH THE ANSWER ALREADY?????? D:
Vocaloid
  • Vocaloid
then we just move everything to one side and use the quadratic formula
Vocaloid
  • Vocaloid
|dw:1447432804982:dw|
carlyleukhardt
  • carlyleukhardt
So the answer is n=0?
Vocaloid
  • Vocaloid
no.

after we apply the quadratic formula:

I guess i will put a random answer because my brain can't handle this type of math ;~;

carlyleukhardt
  • carlyleukhardt
So n= that?
Vocaloid
  • Vocaloid
yeah

Thank you so much :D :D :D
