What two numbers multiply to -396 and add up to 21?




Here we answer the question: "What two numbers multiply to -396 and add up to 21?"

The answer to your question is:

-12 and 33


Below we illustrate and prove that -12 and 33 multiply to -396 and add up to 21:

-12 × 33 = -396
-12 + 33 = 21

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

x2 + 21x - 396 = 0

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

(x - 12 ) (x + 33)

To summarize, since -12 and 33 multiply to -396 and add up 21, you know that the following is true:

x2 + 21x - 396 = (x - 12 ) (x + 33)
