What two numbers multiply to 351 and add up to 40?

Here we answer the question: "What two numbers multiply to 351 and add up to 40?"

The answer to your question is:

13 and 27

Below we illustrate and prove that 13 and 27 multiply to 351 and add up to 40:

13 × 27 = 351
13 + 27 = 40

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

x² + 40x + 351 = 0

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

(x + 13 ) (x + 27)

To summarize, since 13 and 27 multiply to 351 and add up 40, you know that the following is true:

x² + 40x + 351 = (x + 13 ) (x + 27)
