What two numbers multiply to -780 and add up to -151?

Here we answer the question: "What two numbers multiply to -780 and add up to -151?"

The answer to your question is:

-156 and 5

Below we illustrate and prove that -156 and 5 multiply to -780 and add up to -151:

-156 × 5 = -780
-156 + 5 = -151

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

x² - 151x - 780 = 0

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

(x - 156 ) (x + 5)

To summarize, since -156 and 5 multiply to -780 and add up -151, you know that the following is true:

x² - 151x - 780 = (x - 156 ) (x + 5)
