LN(x+3)+LNx=LN4
\n" ); document.write( "LNx(x+3)=LN4
\n" ); document.write( "x(x+3)=4
\n" ); document.write( "x^2 + 3x = 4
\n" ); document.write( "x^2 + 3x - 4 = 0
\n" ); document.write( "(x-4)(x+1) = 0
\n" ); document.write( "x = {-1, 4}
\n" ); document.write( "We can toss out the negative solution (ln of a negative does not make sense), leaving us with:
\n" ); document.write( "x = 4
\n" ); document.write( "
\n" );
