## algebra precalculus – what is the square root of 144

4$ has two roots, yes: $\pm 12$. So $-12$ is a root of 4$.

However, we define the principal square root of $\sqrt {x^2} = |x|$, so in your case, $$\sqrt{144} = \sqrt{12^2} = |12| = 12$$

And your calculator is designed to return the principal square root. See Wolfram Alpha for the distinction: $ is the principal square root (what we mean by $\sqrt x$, given $x\geq 0$), and $-12$ is considered a real root.
