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:

-5 and 134

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

-5 × 134 = -670
-5 + 134 = 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 - 5 ) (x + 134)

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

x² + 129x - 670 = (x - 5 ) (x + 134)
