What two numbers multiply to -12 and add up to -4?

Here we answer the question: "What two numbers multiply to -12 and add up to -4?"

The answer to your question is:

-6 and 2

Below we illustrate and prove that -6 and 2 multiply to -12 and add up to -4:

-6 × 2 = -12
-6 + 2 = -4

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

x² - 4x - 12 = 0

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

(x - 6 ) (x + 2)

To summarize, since -6 and 2 multiply to -12 and add up -4, you know that the following is true:

x² - 4x - 12 = (x - 6 ) (x + 2)
