What two numbers multiply to -869 and add up to 868?

Here we answer the question: "What two numbers multiply to -869 and add up to 868?"

The answer to your question is:

-1 and 869

Below we illustrate and prove that -1 and 869 multiply to -869 and add up to 868:

-1 × 869 = -869
-1 + 869 = 868

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

x² + 868x - 869 = 0

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

(x - 1 ) (x + 869)

To summarize, since -1 and 869 multiply to -869 and add up 868, you know that the following is true:

x² + 868x - 869 = (x - 1 ) (x + 869)
