You can put this solution on YOUR website!
log(x)+log(y)=log(x*y) so:
\n" ); document.write( "log(X)+log(X-7)=log(X+11)+log(2)
\n" ); document.write( "log[(X)(X-7)]=log[(X+11)(2)] Taking anti-logs:
\n" ); document.write( "(X)(X-7)=(X+11)(2)
\n" ); document.write( ".
\n" ); document.write( " $\"X%5E2-7X=2X%2B22\"$
\n" ); document.write( " $\"X%5E2-9X-22=0\"$
\n" ); document.write( " $\"%28X-11%29%28X%2B2%29=0\"$
