What two numbers multiply to -364 and add up to 15?

Here we answer the question: "What two numbers multiply to -364 and add up to 15?"

The answer to your question is:

-13 and 28

Below we illustrate and prove that -13 and 28 multiply to -364 and add up to 15:

-13 × 28 = -364
-13 + 28 = 15

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

x² + 15x - 364 = 0

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

(x - 13 ) (x + 28)

To summarize, since -13 and 28 multiply to -364 and add up 15, you know that the following is true:

x² + 15x - 364 = (x - 13 ) (x + 28)
