What two numbers multiply to -945 and add up to 24?

Here we answer the question: "What two numbers multiply to -945 and add up to 24?"

The answer to your question is:

-21 and 45

Below we illustrate and prove that -21 and 45 multiply to -945 and add up to 24:

-21 × 45 = -945
-21 + 45 = 24

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

x² + 24x - 945 = 0

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

(x - 21 ) (x + 45)

To summarize, since -21 and 45 multiply to -945 and add up 24, you know that the following is true:

x² + 24x - 945 = (x - 21 ) (x + 45)
