What two numbers multiply to 63 and add up to 24?

Here we answer the question: "What two numbers multiply to 63 and add up to 24?"

The answer to your question is:

3 and 21

Below we illustrate and prove that 3 and 21 multiply to 63 and add up to 24:

3 × 21 = 63
3 + 21 = 24

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

x² + 24x + 63 = 0

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

(x + 3 ) (x + 21)

To summarize, since 3 and 21 multiply to 63 and add up 24, you know that the following is true:

x² + 24x + 63 = (x + 3 ) (x + 21)
