well first foil
\r
\n" ); document.write( "\n" ); document.write( "(x-4)(x+4)= -30
\n" ); document.write( "x^2-16 = -30\r
\n" ); document.write( "\n" ); document.write( "now solve
\r
\n" ); document.write( "\n" ); document.write( "x^2-16=-30
\n" ); document.write( "x^2-14=0
\n" ); document.write( "x^2=14
\n" ); document.write( "x = + or - \"sqrt%2814%29\"
\n" ); document.write( "
\n" );
