What two numbers multiply to -556 and add up to 276?

Here we answer the question: "What two numbers multiply to -556 and add up to 276?"

The answer to your question is:

-2 and 278

Below we illustrate and prove that -2 and 278 multiply to -556 and add up to 276:

-2 × 278 = -556
-2 + 278 = 276

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

x² + 276x - 556 = 0

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

(x - 2 ) (x + 278)

To summarize, since -2 and 278 multiply to -556 and add up 276, you know that the following is true:

x² + 276x - 556 = (x - 2 ) (x + 278)
