What two numbers multiply to -140 and add up to 4?

Here we answer the question: "What two numbers multiply to -140 and add up to 4?"

The answer to your question is:

-10 and 14

Below we illustrate and prove that -10 and 14 multiply to -140 and add up to 4:

-10 × 14 = -140
-10 + 14 = 4

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

x² + 4x - 140 = 0

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

(x - 10 ) (x + 14)

To summarize, since -10 and 14 multiply to -140 and add up 4, you know that the following is true:

x² + 4x - 140 = (x - 10 ) (x + 14)
