What two numbers multiply to -395 and add up to 394?

Here we answer the question: "What two numbers multiply to -395 and add up to 394?"

The answer to your question is:

-1 and 395

Below we illustrate and prove that -1 and 395 multiply to -395 and add up to 394:

-1 × 395 = -395
-1 + 395 = 394

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

x² + 394x - 395 = 0

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

(x - 1 ) (x + 395)

To summarize, since -1 and 395 multiply to -395 and add up 394, you know that the following is true:

x² + 394x - 395 = (x - 1 ) (x + 395)
