What two numbers multiply to -858 and add up to 857?

Here we answer the question: "What two numbers multiply to -858 and add up to 857?"

The answer to your question is:

-1 and 858

Below we illustrate and prove that -1 and 858 multiply to -858 and add up to 857:

-1 × 858 = -858
-1 + 858 = 857

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

x² + 857x - 858 = 0

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

(x - 1 ) (x + 858)

To summarize, since -1 and 858 multiply to -858 and add up 857, you know that the following is true:

x² + 857x - 858 = (x - 1 ) (x + 858)
