What two numbers multiply to -390 and add up to -127?

Here we answer the question: "What two numbers multiply to -390 and add up to -127?"

The answer to your question is:

-130 and 3

Below we illustrate and prove that -130 and 3 multiply to -390 and add up to -127:

-130 × 3 = -390
-130 + 3 = -127

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

x² - 127x - 390 = 0

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

(x - 130 ) (x + 3)

To summarize, since -130 and 3 multiply to -390 and add up -127, you know that the following is true:

x² - 127x - 390 = (x - 130 ) (x + 3)
