What two numbers multiply to -870 and add up to -869?

Here we answer the question: "What two numbers multiply to -870 and add up to -869?"

The answer to your question is:

-870 and 1

Below we illustrate and prove that -870 and 1 multiply to -870 and add up to -869:

-870 × 1 = -870
-870 + 1 = -869

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

x² - 869x - 870 = 0

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

(x - 870 ) (x + 1)

To summarize, since -870 and 1 multiply to -870 and add up -869, you know that the following is true:

x² - 869x - 870 = (x - 870 ) (x + 1)
