What two numbers multiply to 840 and add up to -146?

Here we answer the question: "What two numbers multiply to 840 and add up to -146?"

The answer to your question is:

-140 and -6

Below we illustrate and prove that -140 and -6 multiply to 840 and add up to -146:

-140 × -6 = 840
-140 + -6 = -146

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

x² - 146x + 840 = 0

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

(x - 140 ) (x - 6)

To summarize, since -140 and -6 multiply to 840 and add up -146, you know that the following is true:

x² - 146x + 840 = (x - 140 ) (x - 6)
