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

The answer to your question is:

-8 and 88


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

-8 × 88 = -704
-8 + 88 = 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 - 8 ) (x + 88)

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

x2 + 80x - 704 = (x - 8 ) (x + 88)
