What two numbers multiply to -250 and add up to 15?

Here we answer the question: "What two numbers multiply to -250 and add up to 15?"

The answer to your question is:

-10 and 25

Below we illustrate and prove that -10 and 25 multiply to -250 and add up to 15:

-10 × 25 = -250
-10 + 25 = 15

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

x² + 15x - 250 = 0

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

(x - 10 ) (x + 25)

To summarize, since -10 and 25 multiply to -250 and add up 15, you know that the following is true:

x² + 15x - 250 = (x - 10 ) (x + 25)
