Here we answer the question: "What two numbers multiply to -46 and add up to -21?"

The answer to your question is:

-23 and 2


Below we illustrate and prove that -23 and 2 multiply to -46 and add up to -21:

-23 × 2 = -46
-23 + 2 = -21

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

x2 - 21x - 46 = 0

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

(x - 23 ) (x + 2)

To summarize, since -23 and 2 multiply to -46 and add up -21, you know that the following is true:

x2 - 21x - 46 = (x - 23 ) (x + 2)
