What two numbers multiply to -285 and add up to 284?

Here we answer the question: "What two numbers multiply to -285 and add up to 284?"

The answer to your question is:

-1 and 285

Below we illustrate and prove that -1 and 285 multiply to -285 and add up to 284:

-1 × 285 = -285
-1 + 285 = 284

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

x² + 284x - 285 = 0

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

(x - 1 ) (x + 285)

To summarize, since -1 and 285 multiply to -285 and add up 284, you know that the following is true:

x² + 284x - 285 = (x - 1 ) (x + 285)
