What two numbers multiply to 560 and add up to 561?

Here we answer the question: "What two numbers multiply to 560 and add up to 561?"

The answer to your question is:

1 and 560

Below we illustrate and prove that 1 and 560 multiply to 560 and add up to 561:

1 × 560 = 560
1 + 560 = 561

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

x² + 561x + 560 = 0

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

(x + 1 ) (x + 560)

To summarize, since 1 and 560 multiply to 560 and add up 561, you know that the following is true:

x² + 561x + 560 = (x + 1 ) (x + 560)
