What two numbers multiply to -840 and add up to -277?

Here we answer the question: "What two numbers multiply to -840 and add up to -277?"

The answer to your question is:

-280 and 3

Below we illustrate and prove that -280 and 3 multiply to -840 and add up to -277:

-280 × 3 = -840
-280 + 3 = -277

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

x² - 277x - 840 = 0

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

(x - 280 ) (x + 3)

To summarize, since -280 and 3 multiply to -840 and add up -277, you know that the following is true:

x² - 277x - 840 = (x - 280 ) (x + 3)
