What two numbers multiply to 781 and add up to -82?

Here we answer the question: "What two numbers multiply to 781 and add up to -82?"

The answer to your question is:

-71 and -11

Below we illustrate and prove that -71 and -11 multiply to 781 and add up to -82:

-71 × -11 = 781
-71 + -11 = -82

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

x² - 82x + 781 = 0

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

(x - 71 ) (x - 11)

To summarize, since -71 and -11 multiply to 781 and add up -82, you know that the following is true:

x² - 82x + 781 = (x - 71 ) (x - 11)
