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

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

The answer to your question is:

-1 and 906

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

-1 × 906 = -906
-1 + 906 = 905

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

x² + 905x - 906 = 0

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

(x - 1 ) (x + 906)

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

x² + 905x - 906 = (x - 1 ) (x + 906)
