What two numbers multiply to -780 and add up to -124?

Here we answer the question: "What two numbers multiply to -780 and add up to -124?"

The answer to your question is:

-130 and 6

Below we illustrate and prove that -130 and 6 multiply to -780 and add up to -124:

-130 × 6 = -780
-130 + 6 = -124

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

x² - 124x - 780 = 0

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

(x - 130 ) (x + 6)

To summarize, since -130 and 6 multiply to -780 and add up -124, you know that the following is true:

x² - 124x - 780 = (x - 130 ) (x + 6)
