What two numbers multiply to -403 and add up to -402?

Here we answer the question: "What two numbers multiply to -403 and add up to -402?"

The answer to your question is:

-403 and 1

Below we illustrate and prove that -403 and 1 multiply to -403 and add up to -402:

-403 × 1 = -403
-403 + 1 = -402

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

x² - 402x - 403 = 0

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

(x - 403 ) (x + 1)

To summarize, since -403 and 1 multiply to -403 and add up -402, you know that the following is true:

x² - 402x - 403 = (x - 403 ) (x + 1)
