What two numbers multiply to -672 and add up to -221?

Here we answer the question: "What two numbers multiply to -672 and add up to -221?"

The answer to your question is:

-224 and 3

Below we illustrate and prove that -224 and 3 multiply to -672 and add up to -221:

-224 × 3 = -672
-224 + 3 = -221

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

x² - 221x - 672 = 0

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

(x - 224 ) (x + 3)

To summarize, since -224 and 3 multiply to -672 and add up -221, you know that the following is true:

x² - 221x - 672 = (x - 224 ) (x + 3)
