Solve the following equation
\n" ); document.write( "log 7 + log(x − 1) − log(x^2 − 2) − log 2 = 0
\n" ); document.write( "I did [log 7x-7]-[log2x^2-4]=0
\n" ); document.write( "log(7x-7/2x^2-4)=0
\n" ); document.write( "10^0=7x-7/2x^2-4
\n" ); document.write( "1=7x-7/2x^2-4
\n" ); document.write( "multiplied both sides by (2x^2-4)
\n" ); document.write( "2x^2-4=7x-7
\n" ); document.write( "2x^2-7x-3=0 *********** It's good except it should be +3.
\n" ); document.write( "---------------
\n" ); document.write( "2x^2-7x+3=0
\n" ); document.write( "(2x-1)*(x-3) = 0
\n" ); document.write( "x = 3
\n" ); document.write( "x = 1/2 **** x = 1/2 --> log of negative number, not allowed.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
