What two numbers multiply to 780 and add up to -136?

Here we answer the question: "What two numbers multiply to 780 and add up to -136?"

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 -136:

-130 × -6 = 780
-130 + -6 = -136

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

x² - 136x + 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 -136, you know that the following is true:

x² - 136x + 780 = (x - 130 ) (x - 6)
