What two numbers multiply to 840 and add up to -74?

Here we answer the question: "What two numbers multiply to 840 and add up to -74?"

The answer to your question is:

-60 and -14

Below we illustrate and prove that -60 and -14 multiply to 840 and add up to -74:

-60 × -14 = 840
-60 + -14 = -74

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

x² - 74x + 840 = 0

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

(x - 60 ) (x - 14)

To summarize, since -60 and -14 multiply to 840 and add up -74, you know that the following is true:

x² - 74x + 840 = (x - 60 ) (x - 14)
