What two numbers multiply to -859 and add up to 858?

Here we answer the question: "What two numbers multiply to -859 and add up to 858?"

The answer to your question is:

-1 and 859

Below we illustrate and prove that -1 and 859 multiply to -859 and add up to 858:

-1 × 859 = -859
-1 + 859 = 858

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

x² + 858x - 859 = 0

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

(x - 1 ) (x + 859)

To summarize, since -1 and 859 multiply to -859 and add up 858, you know that the following is true:

x² + 858x - 859 = (x - 1 ) (x + 859)
