What two numbers multiply to -252 and add up to -9?

Here we answer the question: "What two numbers multiply to -252 and add up to -9?"

The answer to your question is:

-21 and 12

Below we illustrate and prove that -21 and 12 multiply to -252 and add up to -9:

-21 × 12 = -252
-21 + 12 = -9

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

x² - 9x - 252 = 0

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

(x - 21 ) (x + 12)

To summarize, since -21 and 12 multiply to -252 and add up -9, you know that the following is true:

x² - 9x - 252 = (x - 21 ) (x + 12)
