What two numbers multiply to -656 and add up to -160?

Here we answer the question: "What two numbers multiply to -656 and add up to -160?"

The answer to your question is:

-164 and 4

Below we illustrate and prove that -164 and 4 multiply to -656 and add up to -160:

-164 × 4 = -656
-164 + 4 = -160

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

x² - 160x - 656 = 0

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

(x - 164 ) (x + 4)

To summarize, since -164 and 4 multiply to -656 and add up -160, you know that the following is true:

x² - 160x - 656 = (x - 164 ) (x + 4)
