What two numbers multiply to -425 and add up to -8?

Here we answer the question: "What two numbers multiply to -425 and add up to -8?"

The answer to your question is:

-25 and 17

Below we illustrate and prove that -25 and 17 multiply to -425 and add up to -8:

-25 × 17 = -425
-25 + 17 = -8

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

x² - 8x - 425 = 0

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

(x - 25 ) (x + 17)

To summarize, since -25 and 17 multiply to -425 and add up -8, you know that the following is true:

x² - 8x - 425 = (x - 25 ) (x + 17)
