Here we answer the question: "What two numbers multiply to -788 and add up to 392?"
The answer to your question is:
-2 and 394
Below we illustrate and prove that -2 and 394 multiply to -788 and add up to 392:
-2 × 394 = -788
-2 + 394 = 392
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 392x - 788 = 0
If so, the solution to factor the quadratic equation above is:
(x - 2 ) (x + 394)
To summarize, since -2 and 394 multiply to -788 and add up 392, you know that the following is true:
x2 + 392x - 788 = (x - 2 ) (x + 394)
