What two numbers multiply to -36 and add up to -9?

Here we answer the question: "What two numbers multiply to -36 and add up to -9?"

The answer to your question is:

-12 and 3

Below we illustrate and prove that -12 and 3 multiply to -36 and add up to -9:

-12 × 3 = -36
-12 + 3 = -9

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

x² - 9x - 36 = 0

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

(x - 12 ) (x + 3)

To summarize, since -12 and 3 multiply to -36 and add up -9, you know that the following is true:

x² - 9x - 36 = (x - 12 ) (x + 3)
