What two numbers multiply to 556 and add up to 280?

Here we answer the question: "What two numbers multiply to 556 and add up to 280?"

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 280:

2 × 278 = 556
2 + 278 = 280

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

x² + 280x + 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 280, you know that the following is true:

x² + 280x + 556 = (x + 2 ) (x + 278)
