What two numbers multiply to 139 and add up to -140?

Here we answer the question: "What two numbers multiply to 139 and add up to -140?"

The answer to your question is:

-139 and -1

Below we illustrate and prove that -139 and -1 multiply to 139 and add up to -140:

-139 × -1 = 139
-139 + -1 = -140

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

x² - 140x + 139 = 0

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

(x - 139 ) (x - 1)

To summarize, since -139 and -1 multiply to 139 and add up -140, you know that the following is true:

x² - 140x + 139 = (x - 139 ) (x - 1)
