≈-0.2440169358563

Answer 3

wait I don't get it... how do you solve it?

Answer 4

\[x=(\sqrt{3}+a)/3 ; \approx.0.91\]
\[x=(1-\sqrt{3})/3;\approx -0.2\]

Answer 5

I don't think that is right, because that not one of the options.

Answer 6

wait a minute I'm adjusting the response

Answer 7

quadratic equation formula method

\[9x ^{2} +(-6)x-2=0\] ;
\[ x= (-(-6+\sqrt{(-6)^{2}-4*9(-2}))/2*9)\] ;
\[x=(-(-6)+\sqrt{108})/2*9\] ;
x=(-(-6)+\sqrt{36+(-36)(-2)})/2*9\] ;
\[x=(-(-6)+6\sqrt{3}) /2*9 ; x=(6-6\sqrt{3})/18 ; x=1-\sqrt{3}/3\] ;\[x=\sqrt{3}+1/3; x=(1-\sqrt{3})/3 \]

Answer 8

quadratic equation formula
\[x=(-b+/-\sqrt{b ^{2}-4ac)}/2a\]
