The answer to your question is:

-51 and 9


Below we illustrate and prove that -51 and 9 multiply to -459 and add up to -42:

-51 × 9 = -459
-51 + 9 = -42

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x2 - 42x - 459 = 0

If so, the solution to factor the quadratic equation above is:

(x - 51 ) (x + 9)

To summarize, since -51 and 9 multiply to -459 and add up -42, you know that the following is true:

x2 - 42x - 459 = (x - 51 ) (x + 9)
