x^2+12x-64=0
\n" ); document.write( "x^2+12x=64
\n" ); document.write( "add 36
\n" ); document.write( "x^2+12x+36=64+36
\n" ); document.write( "(x+6)^2=100
\n" ); document.write( "(x+6)^2=10^2
\n" ); document.write( "take the square root
\n" ); document.write( "x+6=+/-10
\n" ); document.write( "x=10-6
\n" ); document.write( "x=4
\n" ); document.write( "OR
\n" ); document.write( "x= -10-6
\n" ); document.write( "x=-16
\n" ); document.write( "
\n" );
