The answer to your question is:

-82 and 4


Below we illustrate and prove that -82 and 4 multiply to -328 and add up to -78:

-82 × 4 = -328
-82 + 4 = -78

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

x2 - 78x - 328 = 0

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

(x - 82 ) (x + 4)

To summarize, since -82 and 4 multiply to -328 and add up -78, you know that the following is true:

x2 - 78x - 328 = (x - 82 ) (x + 4)
