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:

-17 and 25

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

-17 × 25 = -425
-17 + 25 = 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 - 17 ) (x + 25)

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

x² + 8x - 425 = (x - 17 ) (x + 25)
