What two numbers multiply to 670 and add up to -139?

Here we answer the question: "What two numbers multiply to 670 and add up to -139?"

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 -139:

-134 × -5 = 670
-134 + -5 = -139

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

x² - 139x + 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 -139, you know that the following is true:

x² - 139x + 670 = (x - 134 ) (x - 5)
