What two numbers multiply to -802 and add up to 801?

Here we answer the question: "What two numbers multiply to -802 and add up to 801?"

The answer to your question is:

-1 and 802

Below we illustrate and prove that -1 and 802 multiply to -802 and add up to 801:

-1 × 802 = -802
-1 + 802 = 801

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

x² + 801x - 802 = 0

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

(x - 1 ) (x + 802)

To summarize, since -1 and 802 multiply to -802 and add up 801, you know that the following is true:

x² + 801x - 802 = (x - 1 ) (x + 802)
