Algebra.Com's Answer #210925 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! log x + log (x-5) = log 6 \n" ); document.write( "Adding logs --> multiply \n" ); document.write( "log(x*(x-5)) = log(6) \n" ); document.write( "If the logs are equal, so are the arguments \n" ); document.write( "x*(x-5) = 6 \n" ); document.write( " \n" ); document.write( "(x-6)*(x+1) = 0 \n" ); document.write( "x = 6 \n" ); document.write( "-------- \n" ); document.write( "x = -1 BUT there's no log of -1, so it's not an acceptable solution. \n" ); document.write( "x = 6 is it. \n" ); document.write( " \n" ); document.write( " |
