What two numbers multiply to -112 and add up to -9?

Here we answer the question: "What two numbers multiply to -112 and add up to -9?"

The answer to your question is:

-16 and 7

Below we illustrate and prove that -16 and 7 multiply to -112 and add up to -9:

-16 × 7 = -112
-16 + 7 = -9

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

x² - 9x - 112 = 0

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

(x - 16 ) (x + 7)

To summarize, since -16 and 7 multiply to -112 and add up -9, you know that the following is true:

x² - 9x - 112 = (x - 16 ) (x + 7)
