What two numbers multiply to 360 and add up to -123?

Here we answer the question: "What two numbers multiply to 360 and add up to -123?"

The answer to your question is:

-120 and -3

Below we illustrate and prove that -120 and -3 multiply to 360 and add up to -123:

-120 × -3 = 360
-120 + -3 = -123

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

x² - 123x + 360 = 0

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

(x - 120 ) (x - 3)

To summarize, since -120 and -3 multiply to 360 and add up -123, you know that the following is true:

x² - 123x + 360 = (x - 120 ) (x - 3)
