What two numbers multiply to -840 and add up to 46?

Here we answer the question: "What two numbers multiply to -840 and add up to 46?"

The answer to your question is:

-14 and 60

Below we illustrate and prove that -14 and 60 multiply to -840 and add up to 46:

-14 × 60 = -840
-14 + 60 = 46

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

x² + 46x - 840 = 0

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

(x - 14 ) (x + 60)

To summarize, since -14 and 60 multiply to -840 and add up 46, you know that the following is true:

x² + 46x - 840 = (x - 14 ) (x + 60)
