What two numbers multiply to -442 and add up to -21?

Here we answer the question: "What two numbers multiply to -442 and add up to -21?"

The answer to your question is:

-34 and 13

Below we illustrate and prove that -34 and 13 multiply to -442 and add up to -21:

-34 × 13 = -442
-34 + 13 = -21

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

x² - 21x - 442 = 0

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

(x - 34 ) (x + 13)

To summarize, since -34 and 13 multiply to -442 and add up -21, you know that the following is true:

x² - 21x - 442 = (x - 34 ) (x + 13)
