Here we answer the question: "What two numbers multiply to 492 and add up to -127?"

The answer to your question is:

-123 and -4

Below we illustrate and prove that -123 and -4 multiply to 492 and add up to -127:

-123 × -4 = 492
-123 + -4 = -127

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

x² - 127x + 492 = 0

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

(x - 123 ) (x - 4)

To summarize, since -123 and -4 multiply to 492 and add up -127, you know that the following is true:

x² - 127x + 492 = (x - 123 ) (x - 4)
