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:

-21 and 33

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

-21 × 33 = -693
-21 + 33 = 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 - 21 ) (x + 33)

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

x² + 12x - 693 = (x - 21 ) (x + 33)
