What two numbers multiply to -78 and add up to -37?

Here we answer the question: "What two numbers multiply to -78 and add up to -37?"

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 -37:

-39 × 2 = -78
-39 + 2 = -37

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

x² - 37x - 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 -37, you know that the following is true:

x² - 37x - 78 = (x - 39 ) (x + 2)
