What two numbers multiply to 242 and add up to -123?

Here we answer the question: "What two numbers multiply to 242 and add up to -123?"

The answer to your question is:

-121 and -2

Below we illustrate and prove that -121 and -2 multiply to 242 and add up to -123:

-121 × -2 = 242
-121 + -2 = -123

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

x² - 123x + 242 = 0

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

(x - 121 ) (x - 2)

To summarize, since -121 and -2 multiply to 242 and add up -123, you know that the following is true:

x² - 123x + 242 = (x - 121 ) (x - 2)
