Here we answer the question: "What two numbers multiply to -41 and add up to -40?"

The answer to your question is:

-41 and 1

Below we illustrate and prove that -41 and 1 multiply to -41 and add up to -40:

-41 × 1 = -41
-41 + 1 = -40

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

x² - 40x - 41 = 0

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

(x - 41 ) (x + 1)

To summarize, since -41 and 1 multiply to -41 and add up -40, you know that the following is true:

x² - 40x - 41 = (x - 41 ) (x + 1)
