What two numbers multiply to 78 and add up to -41?

Here we answer the question: "What two numbers multiply to 78 and add up to -41?"

The answer to your question is:

-39 and -2

Below we illustrate and prove that -39 and -2 multiply to 78 and add up to -41:

-39 × -2 = 78
-39 + -2 = -41

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

x² - 41x + 78 = 0

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

(x - 39 ) (x - 2)

To summarize, since -39 and -2 multiply to 78 and add up -41, you know that the following is true:

x² - 41x + 78 = (x - 39 ) (x - 2)
