What two numbers multiply to -828 and add up to 827?

Here we answer the question: "What two numbers multiply to -828 and add up to 827?"

The answer to your question is:

-1 and 828

Below we illustrate and prove that -1 and 828 multiply to -828 and add up to 827:

-1 × 828 = -828
-1 + 828 = 827

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

x² + 827x - 828 = 0

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

(x - 1 ) (x + 828)

To summarize, since -1 and 828 multiply to -828 and add up 827, you know that the following is true:

x² + 827x - 828 = (x - 1 ) (x + 828)
