What two numbers multiply to -28 and add up to -12?

Here we answer the question: "What two numbers multiply to -28 and add up to -12?"

The answer to your question is:

-14 and 2

Below we illustrate and prove that -14 and 2 multiply to -28 and add up to -12:

-14 × 2 = -28
-14 + 2 = -12

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

x² - 12x - 28 = 0

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

(x - 14 ) (x + 2)

To summarize, since -14 and 2 multiply to -28 and add up -12, you know that the following is true:

x² - 12x - 28 = (x - 14 ) (x + 2)
