$$\sqrt{8+\sqrt{8+\sqrt{8+\sqrt{8+\sqrt{8+.....}}}}}$$

I know you have to make it equal to x, and then solve somehow.. but I can't quite remember, it's been about a year since doing this.

I know the answer, I want to know HOW. 

Thanks in advance :)

anonymous · Answer

x^2=8+x

chaise · Answer

This gives: 

x^2-x-8=0

-b+sqrt(b^2-4ac)/2a to solve?

Looks correct, but how did you get there? Steps please? If you can.
