You can put this solution on YOUR website!
2x²-4x+2 = 0
\n" ); document.write( "

\r\n" );
document.write( "Divide every number by 2:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "x²-2x+1 = 0\r\n" );
document.write( "\r\n" );
document.write( "Factor the left side:\r\n" );
document.write( "\r\n" );
document.write( "(x-1)(x-1) = 0\r\n" );
document.write( "\r\n" );
document.write( "Use the zero-factor property:\r\n" );
document.write( "\r\n" );
document.write( "x-1 = 0; x-1 = 0\r\n" );
document.write( "  x = 1;   x = 1\r\n" );
document.write( "\r\n" );
document.write( "They are both the same, so there is just one real-number solution.\r\n" );
document.write( "\r\n" );
document.write( "That solution is x = 1.\r\n" );
