Algebra.Com's Answer #225505 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! log (x + 3) + log x = 1 \n" ); document.write( "log x(x + 3) = 1 \n" ); document.write( "x(x + 3) = 10^1 \n" ); document.write( "x^2 + 3x = 10 \n" ); document.write( "x^2 + 3x - 10 = 0 \n" ); document.write( "(x+5)(x-2) = 0 \n" ); document.write( "x = {-5, 2} \n" ); document.write( "Toss out the negative solution, it is an extraneous solution leaving: \n" ); document.write( "x = 2\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
