1. find two numbers:
\n" ); document.write( "Add up
\n" ); document.write( "x+y=23
\n" ); document.write( "and multiply
\n" ); document.write( "x*y= -50
\n" ); document.write( "and these numbers are 25 and -2
\n" ); document.write( "(x-2)(x+25)
\n" ); document.write( "Checking:
\n" ); document.write( "(x-2)(x+25)
\n" ); document.write( "(x*x)+(-2*x)+(25*x)+(-2*25)
\n" ); document.write( "= x^2+(-2x)+(25x)+50
\n" ); document.write( "=x^2+23x-50 \n" ); document.write( "

\n" );
