What two numbers multiply to 121 and add up to -22?

Here we answer the question: "What two numbers multiply to 121 and add up to -22?"

The answer to your question is:

-11 and -11

Below we illustrate and prove that -11 and -11 multiply to 121 and add up to -22:

-11 × -11 = 121
-11 + -11 = -22

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

x² - 22x + 121 = 0

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

(x - 11 ) (x - 11)

To summarize, since -11 and -11 multiply to 121 and add up -22, you know that the following is true:

x² - 22x + 121 = (x - 11 ) (x - 11)
