What two numbers multiply to 920 and add up to -921?

Here we answer the question: "What two numbers multiply to 920 and add up to -921?"

The answer to your question is:

-920 and -1

Below we illustrate and prove that -920 and -1 multiply to 920 and add up to -921:

-920 × -1 = 920
-920 + -1 = -921

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

x² - 921x + 920 = 0

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

(x - 920 ) (x - 1)

To summarize, since -920 and -1 multiply to 920 and add up -921, you know that the following is true:

x² - 921x + 920 = (x - 920 ) (x - 1)
