What two numbers multiply to 14 and add up to 15?

Here we answer the question: "What two numbers multiply to 14 and add up to 15?"

The answer to your question is:

1 and 14

Below we illustrate and prove that 1 and 14 multiply to 14 and add up to 15:

1 × 14 = 14
1 + 14 = 15

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

x² + 15x + 14 = 0

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

(x + 1 ) (x + 14)

To summarize, since 1 and 14 multiply to 14 and add up 15, you know that the following is true:

x² + 15x + 14 = (x + 1 ) (x + 14)
