What two numbers multiply to 384 and add up to 40?

Here we answer the question: "What two numbers multiply to 384 and add up to 40?"

The answer to your question is:

16 and 24

Below we illustrate and prove that 16 and 24 multiply to 384 and add up to 40:

16 × 24 = 384
16 + 24 = 40

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

x² + 40x + 384 = 0

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

(x + 16 ) (x + 24)

To summarize, since 16 and 24 multiply to 384 and add up 40, you know that the following is true:

x² + 40x + 384 = (x + 16 ) (x + 24)
