What two numbers multiply to -946 and add up to -21?

Here we answer the question: "What two numbers multiply to -946 and add up to -21?"

The answer to your question is:

-43 and 22

Below we illustrate and prove that -43 and 22 multiply to -946 and add up to -21:

-43 × 22 = -946
-43 + 22 = -21

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

x² - 21x - 946 = 0

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

(x - 43 ) (x + 22)

To summarize, since -43 and 22 multiply to -946 and add up -21, you know that the following is true:

x² - 21x - 946 = (x - 43 ) (x + 22)
