What two numbers multiply to 840 and add up to -62?

Here we answer the question: "What two numbers multiply to 840 and add up to -62?"

The answer to your question is:

-42 and -20

Below we illustrate and prove that -42 and -20 multiply to 840 and add up to -62:

-42 × -20 = 840
-42 + -20 = -62

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

x² - 62x + 840 = 0

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

(x - 42 ) (x - 20)

To summarize, since -42 and -20 multiply to 840 and add up -62, you know that the following is true:

x² - 62x + 840 = (x - 42 ) (x - 20)
