What two numbers multiply to -840 and add up to -134?

Here we answer the question: "What two numbers multiply to -840 and add up to -134?"

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 -134:

-140 × 6 = -840
-140 + 6 = -134

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

x² - 134x - 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 -134, you know that the following is true:

x² - 134x - 840 = (x - 140 ) (x + 6)
