What two numbers multiply to -123 and add up to -38?

Here we answer the question: "What two numbers multiply to -123 and add up to -38?"

The answer to your question is:

-41 and 3

Below we illustrate and prove that -41 and 3 multiply to -123 and add up to -38:

-41 × 3 = -123
-41 + 3 = -38

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

x² - 38x - 123 = 0

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

(x - 41 ) (x + 3)

To summarize, since -41 and 3 multiply to -123 and add up -38, you know that the following is true:

x² - 38x - 123 = (x - 41 ) (x + 3)
