What two numbers multiply to -24 and add up to 23?

Here we answer the question: "What two numbers multiply to -24 and add up to 23?"

The answer to your question is:

-1 and 24

Below we illustrate and prove that -1 and 24 multiply to -24 and add up to 23:

-1 × 24 = -24
-1 + 24 = 23

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

x² + 23x - 24 = 0

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

(x - 1 ) (x + 24)

To summarize, since -1 and 24 multiply to -24 and add up 23, you know that the following is true:

x² + 23x - 24 = (x - 1 ) (x + 24)
