What two numbers multiply to -192 and add up to -4?

Here we answer the question: "What two numbers multiply to -192 and add up to -4?"

The answer to your question is:

-16 and 12

Below we illustrate and prove that -16 and 12 multiply to -192 and add up to -4:

-16 × 12 = -192
-16 + 12 = -4

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

x² - 4x - 192 = 0

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

(x - 16 ) (x + 12)

To summarize, since -16 and 12 multiply to -192 and add up -4, you know that the following is true:

x² - 4x - 192 = (x - 16 ) (x + 12)
