What two numbers multiply to 432 and add up to 42?

Here we answer the question: "What two numbers multiply to 432 and add up to 42?"

The answer to your question is:

18 and 24

Below we illustrate and prove that 18 and 24 multiply to 432 and add up to 42:

18 × 24 = 432
18 + 24 = 42

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

x² + 42x + 432 = 0

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

(x + 18 ) (x + 24)

To summarize, since 18 and 24 multiply to 432 and add up 42, you know that the following is true:

x² + 42x + 432 = (x + 18 ) (x + 24)
