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:

-105 and -8

Below we illustrate and prove that -105 and -8 multiply to 840 and add up to -113:

-105 × -8 = 840
-105 + -8 = -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 - 105 ) (x - 8)

To summarize, since -105 and -8 multiply to 840 and add up -113, you know that the following is true:

x² - 113x + 840 = (x - 105 ) (x - 8)
