What two numbers multiply to -556 and add up to 555?

Here we answer the question: "What two numbers multiply to -556 and add up to 555?"

The answer to your question is:

-1 and 556

Below we illustrate and prove that -1 and 556 multiply to -556 and add up to 555:

-1 × 556 = -556
-1 + 556 = 555

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

x² + 555x - 556 = 0

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

(x - 1 ) (x + 556)

To summarize, since -1 and 556 multiply to -556 and add up 555, you know that the following is true:

x² + 555x - 556 = (x - 1 ) (x + 556)
