What two numbers multiply to 664 and add up to -170?

Here we answer the question: "What two numbers multiply to 664 and add up to -170?"

The answer to your question is:

-166 and -4

Below we illustrate and prove that -166 and -4 multiply to 664 and add up to -170:

-166 × -4 = 664
-166 + -4 = -170

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

x² - 170x + 664 = 0

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

(x - 166 ) (x - 4)

To summarize, since -166 and -4 multiply to 664 and add up -170, you know that the following is true:

x² - 170x + 664 = (x - 166 ) (x - 4)
