Here we answer the question: "What two numbers multiply to 169 and add up to -170?"

The answer to your question is:

-169 and -1

Below we illustrate and prove that -169 and -1 multiply to 169 and add up to -170:

-169 × -1 = 169
-169 + -1 = -170

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

x² - 170x + 169 = 0

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

(x - 169 ) (x - 1)

To summarize, since -169 and -1 multiply to 169 and add up -170, you know that the following is true:

x² - 170x + 169 = (x - 169 ) (x - 1)
