What two numbers multiply to -670 and add up to -129?

Here we answer the question: "What two numbers multiply to -670 and add up to -129?"

The answer to your question is:

-134 and 5

Below we illustrate and prove that -134 and 5 multiply to -670 and add up to -129:

-134 × 5 = -670
-134 + 5 = -129

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

x² - 129x - 670 = 0

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

(x - 134 ) (x + 5)

To summarize, since -134 and 5 multiply to -670 and add up -129, you know that the following is true:

x² - 129x - 670 = (x - 134 ) (x + 5)
