Here we answer the question: "What two numbers multiply to -770 and add up to 383?"
The answer to your question is:
-2 and 385
Below we illustrate and prove that -2 and 385 multiply to -770 and add up to 383:
-2 × 385 = -770
-2 + 385 = 383
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 383x - 770 = 0
If so, the solution to factor the quadratic equation above is:
(x - 2 ) (x + 385)
To summarize, since -2 and 385 multiply to -770 and add up 383, you know that the following is true:
x2 + 383x - 770 = (x - 2 ) (x + 385)
