What two numbers multiply to -123 and add up to -122?

Here we answer the question: "What two numbers multiply to -123 and add up to -122?"

The answer to your question is:

-123 and 1

Below we illustrate and prove that -123 and 1 multiply to -123 and add up to -122:

-123 × 1 = -123
-123 + 1 = -122

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

x² - 122x - 123 = 0

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

(x - 123 ) (x + 1)

To summarize, since -123 and 1 multiply to -123 and add up -122, you know that the following is true:

x² - 122x - 123 = (x - 123 ) (x + 1)
