$\"log%282%2C%28%28x-2%29%29%29%2Blog%282%2C%28x%29%29=3\"$
\n" ); document.write( " $\"log%282%2C%28x%28x-2%29%29%29=3\"$
\n" ); document.write( " $\"x%28x-2%29=8\"$
\n" ); document.write( " $\"x%5E2-2x-8=0\"$
\n" ); document.write( " $\"%28x-4%29%28x%2B2%29=0\"$
\n" ); document.write( "Two possible solutions:
\n" ); document.write( " $\"x-4=0\"$
\n" ); document.write( " $\"x=4\"$
\n" ); document.write( "and
\n" ); document.write( " $\"x%2B2=0\"$
\n" ); document.write( " $\"x=-2\"$
\n" ); document.write( "However, $\"log%282%2C%28-4%29%29\"$ is not defined so this is not an allowed solution. \n" ); document.write( "
