Answer
$(-\infty,\infty)$
Work Step by Step
Step 1. Rewrite the inequality as $(2x-1)^2\geq0$; we can identify the solution to be all real numbers.
Step 2. We can express the solutions on a real number line as shown in the figure.
Step 3. We can express the solutions in interval notation as $(-\infty,\infty)$
