What two numbers multiply to 56 and add up to 18?

Here we answer the question: "What two numbers multiply to 56 and add up to 18?"

The answer to your question is:

4 and 14

Below we illustrate and prove that 4 and 14 multiply to 56 and add up to 18:

4 × 14 = 56
4 + 14 = 18

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

x² + 18x + 56 = 0

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

(x + 4 ) (x + 14)

To summarize, since 4 and 14 multiply to 56 and add up 18, you know that the following is true:

x² + 18x + 56 = (x + 4 ) (x + 14)
