What two numbers multiply to 345 and add up to 38?

Here we answer the question: "What two numbers multiply to 345 and add up to 38?"

The answer to your question is:

15 and 23

Below we illustrate and prove that 15 and 23 multiply to 345 and add up to 38:

15 × 23 = 345
15 + 23 = 38

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

x² + 38x + 345 = 0

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

(x + 15 ) (x + 23)

To summarize, since 15 and 23 multiply to 345 and add up 38, you know that the following is true:

x² + 38x + 345 = (x + 15 ) (x + 23)
