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

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

The answer to your question is:

-122 and -1

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

-122 × -1 = 122
-122 + -1 = -123

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

x² - 123x + 122 = 0

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

(x - 122 ) (x - 1)

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

x² - 123x + 122 = (x - 122 ) (x - 1)
