solve the following equation
\n" ); document.write( "ln(x-1)+lnx=ln6
\n" ); document.write( "=ln(x-1)(x)=ln6
\n" ); document.write( "ln(x^2-x)=ln6
\n" ); document.write( "x^2-x=6
\n" ); document.write( "x^2-x-6=0
\n" ); document.write( "solve by factoring
\n" ); document.write( "(x-3)(x+2)=0
\n" ); document.write( "ans:x=3
\n" ); document.write( " x=-2(reject,logarithm >0)\r
\n" ); document.write( "\n" ); document.write( "check:
\n" ); document.write( "ln(x-1)+lnx=ln6
\n" ); document.write( "ln(3-1)+ln(3)=ln6
\n" ); document.write( ".693+1.099=1.7917
\n" ); document.write( " 1.792=1.7917\r
