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

4. anonymous

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

5. anonymous

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

wait a minute I'm adjusting the response

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\] ; $x=(-(-6)+6\sqrt{3}) /2*9 ; x=(6-6\sqrt{3})/18 ; x=1-\sqrt{3}/3$ ;$x=\sqrt{3}+1/3; x=(1-\sqrt{3})/3$

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