1. The problem is to rewrite the quadratic formula expression for $x$ in a proper, clear mathematical format without solving it.
2. The given expression is:
$$x=\frac{4(L+W)\pm \sqrt{[4(L+W)]^{2}-4(12)(LW)}}{2(12)}$$
3. This is a quadratic formula of the form:
$$x=\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$$
where $a=12$, $b=-4(L+W)$ (note the sign), and $c=LW$.
4. To write it properly, ensure the numerator and denominator are clear, and the signs are correct:
$$x=\frac{4(L+W) \pm \sqrt{\left[4(L+W)\right]^2 - 4 \times 12 \times LW}}{2 \times 12}$$
5. Simplify the denominator:
$$x=\frac{4(L+W) \pm \sqrt{16(L+W)^2 - 48LW}}{24}$$
6. This is the proper formatted expression without solving for $x$.
