What two numbers multiply to -861 and add up to 284?

Here we answer the question: "What two numbers multiply to -861 and add up to 284?"

The answer to your question is:

-3 and 287

Below we illustrate and prove that -3 and 287 multiply to -861 and add up to 284:

-3 × 287 = -861
-3 + 287 = 284

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

x² + 284x - 861 = 0

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

(x - 3 ) (x + 287)

To summarize, since -3 and 287 multiply to -861 and add up 284, you know that the following is true:

x² + 284x - 861 = (x - 3 ) (x + 287)
