What two numbers multiply to -840 and add up to -11?

Here we answer the question: "What two numbers multiply to -840 and add up to -11?"

The answer to your question is:

-35 and 24

Below we illustrate and prove that -35 and 24 multiply to -840 and add up to -11:

-35 × 24 = -840
-35 + 24 = -11

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

x² - 11x - 840 = 0

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

(x - 35 ) (x + 24)

To summarize, since -35 and 24 multiply to -840 and add up -11, you know that the following is true:

x² - 11x - 840 = (x - 35 ) (x + 24)
