What two numbers multiply to -124 and add up to -123?

Here we answer the question: "What two numbers multiply to -124 and add up to -123?"

The answer to your question is:

-124 and 1

Below we illustrate and prove that -124 and 1 multiply to -124 and add up to -123:

-124 × 1 = -124
-124 + 1 = -123

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

x² - 123x - 124 = 0

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

(x - 124 ) (x + 1)

To summarize, since -124 and 1 multiply to -124 and add up -123, you know that the following is true:

x² - 123x - 124 = (x - 124 ) (x + 1)
