What two numbers multiply to 280 and add up to 38?

Here we answer the question: "What two numbers multiply to 280 and add up to 38?"

The answer to your question is:

10 and 28

Below we illustrate and prove that 10 and 28 multiply to 280 and add up to 38:

10 × 28 = 280
10 + 28 = 38

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

x² + 38x + 280 = 0

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

(x + 10 ) (x + 28)

To summarize, since 10 and 28 multiply to 280 and add up 38, you know that the following is true:

x² + 38x + 280 = (x + 10 ) (x + 28)
