What two numbers multiply to 120 and add up to -121?

Here we answer the question: "What two numbers multiply to 120 and add up to -121?"

The answer to your question is:

-120 and -1

Below we illustrate and prove that -120 and -1 multiply to 120 and add up to -121:

-120 × -1 = 120
-120 + -1 = -121

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

x² - 121x + 120 = 0

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

(x - 120 ) (x - 1)

To summarize, since -120 and -1 multiply to 120 and add up -121, you know that the following is true:

x² - 121x + 120 = (x - 120 ) (x - 1)
