What two numbers multiply to -487 and add up to 486?

Here we answer the question: "What two numbers multiply to -487 and add up to 486?"

The answer to your question is:

-1 and 487

Below we illustrate and prove that -1 and 487 multiply to -487 and add up to 486:

-1 × 487 = -487
-1 + 487 = 486

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

x² + 486x - 487 = 0

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

(x - 1 ) (x + 487)

To summarize, since -1 and 487 multiply to -487 and add up 486, you know that the following is true:

x² + 486x - 487 = (x - 1 ) (x + 487)
