What two numbers multiply to -369 and add up to 120?

Here we answer the question: "What two numbers multiply to -369 and add up to 120?"

The answer to your question is:

-3 and 123

Below we illustrate and prove that -3 and 123 multiply to -369 and add up to 120:

-3 × 123 = -369
-3 + 123 = 120

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

x² + 120x - 369 = 0

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

(x - 3 ) (x + 123)

To summarize, since -3 and 123 multiply to -369 and add up 120, you know that the following is true:

x² + 120x - 369 = (x - 3 ) (x + 123)
