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:

-45 and 21

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

-45 × 21 = -945
-45 + 21 = -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 - 45 ) (x + 21)

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

x² - 24x - 945 = (x - 45 ) (x + 21)
