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
