\n" ); document.write( "------
\n" ); document.write( "4x^2 + 12x = 3
\n" ); document.write( "4(x^2 + 3x)= 3
\n" ); document.write( "(x^2 + 3x + (3/2)^2) = (3/4) + (3/2)^2
\n" ); document.write( "(x+(3/2))^2 = (3+9)/4
\n" ); document.write( "-----
\n" ); document.write( "(x+(3/2))^2 = 13/4
\n" ); document.write( "----------------------
