Question

What is L1

Answer 1

would \[L_1\] be \[\frac{ 1-\sqrt{5} }{ 2 }\]

Answer 2

@Mertsj

Answer 3

\[L^2+L-1=0\]
\[L _{1}\] and \[L _{2}\]
are the solutions to that equation.

Answer 4

a=1 b=1, and c =-1

Answer 5

\[L=\frac{-1\pm \sqrt{1-4(1)(-1)}}{2}\]

Answer 6

Yes. You have L_1 right.

Answer 7

and below that, it says \[0<L_1<L_2\] but the lesser solution (L_1) has a negative value but L_1 is suppose to be greater than 0
it is confusing me

Answer 8

I see your point. L_1 is clearly negative. There must be a typo.

Answer 9

that's what i thought, thanks
