The Modulus Function '| |' is defined as:
\(\rm |x|=\left\{\begin{matrix}\rm \ \ x, &\rm x>0\\\rm \ \ 0, & \rm x=0 \\\rm -x, &\rm x<0\\\end{matrix}\right.\)
Calculation:
Since the modulus function '||' always returns a positive value or 0, its not possible to have -2 as the value of modulus of any expression.
Hence, |x + 2| = -2 has no solution.
