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:

-22 and 43

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

-22 × 43 = -946
-22 + 43 = 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 - 22 ) (x + 43)

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

x² + 21x - 946 = (x - 22 ) (x + 43)
