What two numbers multiply to 560 and add up to 87?

Here we answer the question: "What two numbers multiply to 560 and add up to 87?"

The answer to your question is:

7 and 80

Below we illustrate and prove that 7 and 80 multiply to 560 and add up to 87:

7 × 80 = 560
7 + 80 = 87

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

x² + 87x + 560 = 0

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

(x + 7 ) (x + 80)

To summarize, since 7 and 80 multiply to 560 and add up 87, you know that the following is true:

x² + 87x + 560 = (x + 7 ) (x + 80)
