What two numbers multiply to -806 and add up to -401?

Here we answer the question: "What two numbers multiply to -806 and add up to -401?"

The answer to your question is:

-403 and 2

Below we illustrate and prove that -403 and 2 multiply to -806 and add up to -401:

-403 × 2 = -806
-403 + 2 = -401

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

x² - 401x - 806 = 0

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

(x - 403 ) (x + 2)

To summarize, since -403 and 2 multiply to -806 and add up -401, you know that the following is true:

x² - 401x - 806 = (x - 403 ) (x + 2)
