What two numbers multiply to 560 and add up to 66?

Here we answer the question: "What two numbers multiply to 560 and add up to 66?"

The answer to your question is:

10 and 56

Below we illustrate and prove that 10 and 56 multiply to 560 and add up to 66:

10 × 56 = 560
10 + 56 = 66

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

x² + 66x + 560 = 0

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

(x + 10 ) (x + 56)

To summarize, since 10 and 56 multiply to 560 and add up 66, you know that the following is true:

x² + 66x + 560 = (x + 10 ) (x + 56)
