What two numbers multiply to -609 and add up to -8?

Here we answer the question: "What two numbers multiply to -609 and add up to -8?"

The answer to your question is:

-29 and 21

Below we illustrate and prove that -29 and 21 multiply to -609 and add up to -8:

-29 × 21 = -609
-29 + 21 = -8

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

x² - 8x - 609 = 0

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

(x - 29 ) (x + 21)

To summarize, since -29 and 21 multiply to -609 and add up -8, you know that the following is true:

x² - 8x - 609 = (x - 29 ) (x + 21)
