What two numbers multiply to 656 and add up to -168?

Here we answer the question: "What two numbers multiply to 656 and add up to -168?"

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 -168:

-164 × -4 = 656
-164 + -4 = -168

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

x² - 168x + 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 -168, you know that the following is true:

x² - 168x + 656 = (x - 164 ) (x - 4)
