What two numbers multiply to -690 and add up to -109?

Here we answer the question: "What two numbers multiply to -690 and add up to -109?"

The answer to your question is:

-115 and 6

Below we illustrate and prove that -115 and 6 multiply to -690 and add up to -109:

-115 × 6 = -690
-115 + 6 = -109

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

x² - 109x - 690 = 0

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

(x - 115 ) (x + 6)

To summarize, since -115 and 6 multiply to -690 and add up -109, you know that the following is true:

x² - 109x - 690 = (x - 115 ) (x + 6)
