What two numbers multiply to -891 and add up to -70?

Here we answer the question: "What two numbers multiply to -891 and add up to -70?"

The answer to your question is:

-81 and 11

Below we illustrate and prove that -81 and 11 multiply to -891 and add up to -70:

-81 × 11 = -891
-81 + 11 = -70

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

x² - 70x - 891 = 0

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

(x - 81 ) (x + 11)

To summarize, since -81 and 11 multiply to -891 and add up -70, you know that the following is true:

x² - 70x - 891 = (x - 81 ) (x + 11)
