What two numbers multiply to 905 and add up to -906?

Here we answer the question: "What two numbers multiply to 905 and add up to -906?"

The answer to your question is:

-905 and -1

Below we illustrate and prove that -905 and -1 multiply to 905 and add up to -906:

-905 × -1 = 905
-905 + -1 = -906

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

x² - 906x + 905 = 0

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

(x - 905 ) (x - 1)

To summarize, since -905 and -1 multiply to 905 and add up -906, you know that the following is true:

x² - 906x + 905 = (x - 905 ) (x - 1)
