Another Answer:-
They are: 3.618 and 1.382 rounded to 3 decimal places
A more accurate result can be found by using the quadratic equation formula
7.5516 and 70.4484 (approx)
The numbers are: 6+2*sq rt of 6 and 6-2*sq rt of 6.
2+21=23 2*21=42 (* is another symbol for multiply)

8, 5 and 2
-2
The numbers are: 6+2*sq rt of 6 and 6-2*sq rt of 6.
(9 - √89)/2 ≈ -0.217 and (9 + √89)/2 ≈ 9.217
2+21=23 2*21=42 (* is another symbol for multiply)
-15
-2 and -4 do that.
2 and 2
