What two numbers multiply to 660 and add up to -223?

Here we answer the question: "What two numbers multiply to 660 and add up to -223?"

The answer to your question is:

-220 and -3

Below we illustrate and prove that -220 and -3 multiply to 660 and add up to -223:

-220 × -3 = 660
-220 + -3 = -223

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

x² - 223x + 660 = 0

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

(x - 220 ) (x - 3)

To summarize, since -220 and -3 multiply to 660 and add up -223, you know that the following is true:

x² - 223x + 660 = (x - 220 ) (x - 3)
