What two numbers multiply to -336 and add up to 5?

Here we answer the question: "What two numbers multiply to -336 and add up to 5?"

The answer to your question is:

-16 and 21

Below we illustrate and prove that -16 and 21 multiply to -336 and add up to 5:

-16 × 21 = -336
-16 + 21 = 5

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

x² + 5x - 336 = 0

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

(x - 16 ) (x + 21)

To summarize, since -16 and 21 multiply to -336 and add up 5, you know that the following is true:

x² + 5x - 336 = (x - 16 ) (x + 21)
