What two numbers multiply to 390 and add up to -41?

Here we answer the question: "What two numbers multiply to 390 and add up to -41?"

The answer to your question is:

-26 and -15

Below we illustrate and prove that -26 and -15 multiply to 390 and add up to -41:

-26 × -15 = 390
-26 + -15 = -41

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

x² - 41x + 390 = 0

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

(x - 26 ) (x - 15)

To summarize, since -26 and -15 multiply to 390 and add up -41, you know that the following is true:

x² - 41x + 390 = (x - 26 ) (x - 15)
