Question

:)

Answer 1

\[\frac{ x (x+8)+20*(x+2)}{ (x+2)(x+8) }= 2\]

Answer 2

x(x+8)+20(x+2)=2(x+2)(x+8)
now open the bracket and do further calculations

Answer 3

yeah
-x^2+8x+8=0
or x^2-8x-8=0

Answer 4

solve the equation now

Answer 5

I don't get that exactly. I get \[x=4 \pm 2\sqrt{2}\]

Answer 6

\[\frac{ -(-8) \pm \sqrt{64-4*8} }{ 2 }\]

Answer 7

\[\frac{ 8 \pm \sqrt{32} }{ 2 }\]

Answer 8

Making sense, @EcoBoost ?

Answer 9

Ok. Let me know if you got to here. :)

Answer 10

Oh wait!

Answer 11

I didn't plug in my c as negative!

Answer 12

I used the second one.

Answer 13

I like for the coefficient of x^2 to be positive.

Answer 14

But either one works :)

Answer 15

And now I get \[4 \pm 2\sqrt{6}\]

Answer 16

No worries :)
