Here we answer the question: "What two numbers multiply to -774 and add up to -385?"
The answer to your question is:
-387 and 2
Below we illustrate and prove that -387 and 2 multiply to -774 and add up to -385:
-387 × 2 = -774
-387 + 2 = -385
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 385x - 774 = 0
If so, the solution to factor the quadratic equation above is:
(x - 387 ) (x + 2)
To summarize, since -387 and 2 multiply to -774 and add up -385, you know that the following is true:
x2 - 385x - 774 = (x - 387 ) (x + 2)
