2log3 X-log3(X+4) = 2
\n" ); document.write( ":
\n" ); document.write( "log(3) (x^2 / (x+4)) = 2
\n" ); document.write( ":
\n" ); document.write( "Note that 2log(3) x = log(3) x^2, also used log definition of division
\n" ); document.write( ":
\n" ); document.write( "x^2 / (x+4) = 3^2 = 9
\n" ); document.write( ":
\n" ); document.write( "Note used definition of logarithm
\n" ); document.write( ":
\n" ); document.write( "x^2 = 9(x+4)
\n" ); document.write( ":
\n" ); document.write( "x^2 -9x -36 = 0
