Detailed Solution
Download Solution PDFसंकल्पना:
मापांक फलन '| |' को निम्न रूप में परिभाषित किया गया है:
\(\rm |x|=\left\{\begin{matrix}\rm \ \ x, &\rm x>0\\\rm \ \ 0, & \rm x=0 \\\rm -x, &\rm x<0\\\end{matrix}\right.\)
गणना:
चूँकि मापांक फलन '||' सदैव एक धनात्मक मान या 0 वापस करता है, इसलिए किसी भी समीकरण के मापांक के मान के रूप में -2 प्राप्त होना संभव नहीं है।
अतः |x + 2| = -2 में कोई हल नहीं है।
