What two numbers multiply to -704 and add up to -80?

Here we answer the question: "What two numbers multiply to -704 and add up to -80?"

The answer to your question is:

-88 and 8

Below we illustrate and prove that -88 and 8 multiply to -704 and add up to -80:

-88 × 8 = -704
-88 + 8 = -80

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

x² - 80x - 704 = 0

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

(x - 88 ) (x + 8)

To summarize, since -88 and 8 multiply to -704 and add up -80, you know that the following is true:

x² - 80x - 704 = (x - 88 ) (x + 8)
