What two numbers multiply to 840 and add up to -283?

Here we answer the question: "What two numbers multiply to 840 and add up to -283?"

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 -283:

-280 × -3 = 840
-280 + -3 = -283

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

x² - 283x + 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 -283, you know that the following is true:

x² - 283x + 840 = (x - 280 ) (x - 3)
