What two numbers multiply to 14 and add up to -15?

Here we answer the question: "What two numbers multiply to 14 and add up to -15?"

The answer to your question is:

-14 and -1

Below we illustrate and prove that -14 and -1 multiply to 14 and add up to -15:

-14 × -1 = 14
-14 + -1 = -15

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

x² - 15x + 14 = 0

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

(x - 14 ) (x - 1)

To summarize, since -14 and -1 multiply to 14 and add up -15, you know that the following is true:

x² - 15x + 14 = (x - 14 ) (x - 1)
