What two numbers multiply to -777 and add up to 256?

Here we answer the question: "What two numbers multiply to -777 and add up to 256?"

The answer to your question is:

-3 and 259

Below we illustrate and prove that -3 and 259 multiply to -777 and add up to 256:

-3 × 259 = -777
-3 + 259 = 256

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

x² + 256x - 777 = 0

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

(x - 3 ) (x + 259)

To summarize, since -3 and 259 multiply to -777 and add up 256, you know that the following is true:

x² + 256x - 777 = (x - 3 ) (x + 259)
