What two numbers multiply to 336 and add up to 40?

Here we answer the question: "What two numbers multiply to 336 and add up to 40?"

The answer to your question is:

12 and 28

Below we illustrate and prove that 12 and 28 multiply to 336 and add up to 40:

12 × 28 = 336
12 + 28 = 40

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

x² + 40x + 336 = 0

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

(x + 12 ) (x + 28)

To summarize, since 12 and 28 multiply to 336 and add up 40, you know that the following is true:

x² + 40x + 336 = (x + 12 ) (x + 28)
