The square root function needs a non-negative argument.

Break up the number line into 3 regions.
Region 1:(,)
Region 2:(,)
Region 3:(,)
Choose a point in the region, not an endpoint.
Test the inequality.
If the inequality is satisfied, the region is part of the solution.
.

.
Region 1:

True, this region is part of the solution.
.
.
.
Region 2:

False, this region is not part of the solution.
.
.
.
Region 3:

True, this region is part of the solution.

Since also solves the inequality, it is also included.
is not included in any solution region because it leads to a division by zero.
