Here we answer the question: "What two numbers multiply to -782 and add up to -389?"
The answer to your question is:
-391 and 2
Below we illustrate and prove that -391 and 2 multiply to -782 and add up to -389:
-391 × 2 = -782
-391 + 2 = -389
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 389x - 782 = 0
If so, the solution to factor the quadratic equation above is:
(x - 391 ) (x + 2)
To summarize, since -391 and 2 multiply to -782 and add up -389, you know that the following is true:
x2 - 389x - 782 = (x - 391 ) (x + 2)
