What two numbers multiply to 391 and add up to 40?




Here we answer the question: "What two numbers multiply to 391 and add up to 40?"

The answer to your question is:

17 and 23


Below we illustrate and prove that 17 and 23 multiply to 391 and add up to 40:

17 × 23 = 391
17 + 23 = 40

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

x2 + 40x + 391 = 0

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

(x + 17 ) (x + 23)

To summarize, since 17 and 23 multiply to 391 and add up 40, you know that the following is true:

x2 + 40x + 391 = (x + 17 ) (x + 23)
