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:

-11 and 81

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

-11 × 81 = -891
-11 + 81 = 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 - 11 ) (x + 81)

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

x² + 70x - 891 = (x - 11 ) (x + 81)
