$n_1=-\frac{1}{3}+1.31i\\n_2=-\frac{1}{3}-1.31i$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have that the quadratic formula is:

$n=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

2. To solve the quadratic equation you must substitute the values, you have that:

$a=6\\b=4\\c=11$

Then:

$n=\frac{-4+/-\sqrt{4^{2}-4(6)(11)}}{2(6)}$

3, Therefore, you obtain the following result:

$n_1=-\frac{1}{3}+1.31i\\n_2=-\frac{1}{3}-1.31i$
