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:

-80 and -7

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

-80 × -7 = 560
-80 + -7 = -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 - 80 ) (x - 7)

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

x² - 87x + 560 = (x - 80 ) (x - 7)
