You can put this solution on YOUR website!
To get solutions of 3 and 7, then just use (x-3) and (x-7)\r
\n" ); document.write( "\n" ); document.write( "(x-3)(x-7)
\n" ); document.write( "=x(x-7)-3(x-7)
\n" ); document.write( "=x^2-7x -3x+21
\n" ); document.write( "x^2-10x +21
\n" ); document.write( "the quadratic equation is\r
\n" ); document.write( "\n" ); document.write( "x^2-10x+21=0 \n" ); document.write( "
\n" );
