What two numbers multiply to 38 and add up to -39?

Here we answer the question: "What two numbers multiply to 38 and add up to -39?"

The answer to your question is:

-38 and -1

Below we illustrate and prove that -38 and -1 multiply to 38 and add up to -39:

-38 × -1 = 38
-38 + -1 = -39

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

x² - 39x + 38 = 0

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

(x - 38 ) (x - 1)

To summarize, since -38 and -1 multiply to 38 and add up -39, you know that the following is true:

x² - 39x + 38 = (x - 38 ) (x - 1)
