What two numbers multiply to -12 and add up to -1?

Here we answer the question: "What two numbers multiply to -12 and add up to -1?"

The answer to your question is:

-4 and 3

Below we illustrate and prove that -4 and 3 multiply to -12 and add up to -1:

-4 × 3 = -12
-4 + 3 = -1

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

x² - 1x - 12 = 0

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

(x - 4 ) (x + 3)

To summarize, since -4 and 3 multiply to -12 and add up -1, you know that the following is true:

x² - 1x - 12 = (x - 4 ) (x + 3)
