What two numbers multiply to -566 and add up to 565?

Here we answer the question: "What two numbers multiply to -566 and add up to 565?"

The answer to your question is:

-1 and 566

Below we illustrate and prove that -1 and 566 multiply to -566 and add up to 565:

-1 × 566 = -566
-1 + 566 = 565

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

x² + 565x - 566 = 0

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

(x - 1 ) (x + 566)

To summarize, since -1 and 566 multiply to -566 and add up 565, you know that the following is true:

x² + 565x - 566 = (x - 1 ) (x + 566)
