The interval notation is

Step-by-step explanation:
The inequality is

Let us complete the square, we get,

Simplifying, we have,


Adding both sides of the equation by 11, we get,

Since, we know that for
, if n is even then
![-\sqrt[n]{a}<u<\sqrt[n]{a}](https://img.qammunity.org/2021/formulas/mathematics/college/upx8q7nburkohiuzu5cvag2icz0cezobhj.png)
Thus, writing the above expression in this form, we get,

Also, if
then
and

Then ,we have,
and

Solving the inequalities, we get,
and

Merging the intervals, we have,

Hence, writing the solution in interval notation, we have,

Therefore, the answer is
