Let the two numbers be m and n. Then:
\n" ); document.write( "mn=-0.25 and m+n=-1
\n" ); document.write( "So:
\n" ); document.write( "m=-1-n
\n" ); document.write( "(-1-n)n=-0.25
\n" ); document.write( "-n-n²=-0.25
\n" ); document.write( "n²+n-0.25=0
\n" ); document.write( "Using the quadratic formula, we get two roots: 0.207106781187 and -1.20710678119, as m and n. ☺☺☺☺
