What two numbers multiply to -812 and add up to 811?

Here we answer the question: "What two numbers multiply to -812 and add up to 811?"

The answer to your question is:

-1 and 812

Below we illustrate and prove that -1 and 812 multiply to -812 and add up to 811:

-1 × 812 = -812
-1 + 812 = 811

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

x² + 811x - 812 = 0

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

(x - 1 ) (x + 812)

To summarize, since -1 and 812 multiply to -812 and add up 811, you know that the following is true:

x² + 811x - 812 = (x - 1 ) (x + 812)
