What two numbers multiply to -840 and add up to -113?

Here we answer the question: "What two numbers multiply to -840 and add up to -113?"

The answer to your question is:

-120 and 7

Below we illustrate and prove that -120 and 7 multiply to -840 and add up to -113:

-120 × 7 = -840
-120 + 7 = -113

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

x² - 113x - 840 = 0

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

(x - 120 ) (x + 7)

To summarize, since -120 and 7 multiply to -840 and add up -113, you know that the following is true:

x² - 113x - 840 = (x - 120 ) (x + 7)
