What two numbers multiply to -985 and add up to 984?

Here we answer the question: "What two numbers multiply to -985 and add up to 984?"

The answer to your question is:

-1 and 985

Below we illustrate and prove that -1 and 985 multiply to -985 and add up to 984:

-1 × 985 = -985
-1 + 985 = 984

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

x² + 984x - 985 = 0

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

(x - 1 ) (x + 985)

To summarize, since -1 and 985 multiply to -985 and add up 984, you know that the following is true:

x² + 984x - 985 = (x - 1 ) (x + 985)
