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

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

The answer to your question is:

-1 and 140

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

-1 × 140 = -140
-1 + 140 = 139

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

x² + 139x - 140 = 0

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

(x - 1 ) (x + 140)

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

x² + 139x - 140 = (x - 1 ) (x + 140)
