Here we answer the question: "What two numbers multiply to -690 and add up to -59?"

The answer to your question is:

-69 and 10

Below we illustrate and prove that -69 and 10 multiply to -690 and add up to -59:

-69 × 10 = -690
-69 + 10 = -59

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

x² - 59x - 690 = 0

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

(x - 69 ) (x + 10)

To summarize, since -69 and 10 multiply to -690 and add up -59, you know that the following is true:

x² - 59x - 690 = (x - 69 ) (x + 10)
