What two numbers multiply to 868 and add up to -221?

Here we answer the question: "What two numbers multiply to 868 and add up to -221?"

The answer to your question is:

-217 and -4

Below we illustrate and prove that -217 and -4 multiply to 868 and add up to -221:

-217 × -4 = 868
-217 + -4 = -221

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

x² - 221x + 868 = 0

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

(x - 217 ) (x - 4)

To summarize, since -217 and -4 multiply to 868 and add up -221, you know that the following is true:

x² - 221x + 868 = (x - 217 ) (x - 4)
