What two numbers multiply to 657 and add up to -222?

Here we answer the question: "What two numbers multiply to 657 and add up to -222?"

The answer to your question is:

-219 and -3

Below we illustrate and prove that -219 and -3 multiply to 657 and add up to -222:

-219 × -3 = 657
-219 + -3 = -222

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

x² - 222x + 657 = 0

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

(x - 219 ) (x - 3)

To summarize, since -219 and -3 multiply to 657 and add up -222, you know that the following is true:

x² - 222x + 657 = (x - 219 ) (x - 3)
