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:

-6 and 130

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

-6 × 130 = -780
-6 + 130 = 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 - 6 ) (x + 130)

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

x² + 124x - 780 = (x - 6 ) (x + 130)
