What two numbers multiply to -486 and add up to 485?

Here we answer the question: "What two numbers multiply to -486 and add up to 485?"

The answer to your question is:

-1 and 486

Below we illustrate and prove that -1 and 486 multiply to -486 and add up to 485:

-1 × 486 = -486
-1 + 486 = 485

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

x² + 485x - 486 = 0

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

(x - 1 ) (x + 486)

To summarize, since -1 and 486 multiply to -486 and add up 485, you know that the following is true:

x² + 485x - 486 = (x - 1 ) (x + 486)
