What two numbers multiply to -840 and add up to -97?

Here we answer the question: "What two numbers multiply to -840 and add up to -97?"

The answer to your question is:

-105 and 8

Below we illustrate and prove that -105 and 8 multiply to -840 and add up to -97:

-105 × 8 = -840
-105 + 8 = -97

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

x² - 97x - 840 = 0

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

(x - 105 ) (x + 8)

To summarize, since -105 and 8 multiply to -840 and add up -97, you know that the following is true:

x² - 97x - 840 = (x - 105 ) (x + 8)
