What two numbers multiply to -16 and add up to -6?

Here we answer the question: "What two numbers multiply to -16 and add up to -6?"

The answer to your question is:

-8 and 2

Below we illustrate and prove that -8 and 2 multiply to -16 and add up to -6:

-8 × 2 = -16
-8 + 2 = -6

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

x² - 6x - 16 = 0

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

(x - 8 ) (x + 2)

To summarize, since -8 and 2 multiply to -16 and add up -6, you know that the following is true:

x² - 6x - 16 = (x - 8 ) (x + 2)
