4x²-32x+164=0
\n" ); document.write( "4x²-32x=-164
\n" ); document.write( "4(x²-8x)=-164
\n" ); document.write( "x²-8x=-41 （-8/2）²=16
\n" ); document.write( "x²-8x+16=-41+16 completing the square
\n" ); document.write( "（x-4)(x-4)=-25
\n" ); document.write( "(x-4)²=-25 factored form
\n" ); document.write( "x=+√25+4 x=+5+4 x=9
\n" ); document.write( "x=-√25+4 x=-5+4 x=-1 （√25=5）\r
\n" ); document.write( "\n" ); document.write( "so x=9，-1 \n" ); document.write( "

\n" );
