What two numbers multiply to -693 and add up to -12?

Here we answer the question: "What two numbers multiply to -693 and add up to -12?"

The answer to your question is:

-33 and 21

Below we illustrate and prove that -33 and 21 multiply to -693 and add up to -12:

-33 × 21 = -693
-33 + 21 = -12

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

x² - 12x - 693 = 0

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

(x - 33 ) (x + 21)

To summarize, since -33 and 21 multiply to -693 and add up -12, you know that the following is true:

x² - 12x - 693 = (x - 33 ) (x + 21)
