What two numbers multiply to -986 and add up to 985?

Here we answer the question: "What two numbers multiply to -986 and add up to 985?"

The answer to your question is:

-1 and 986

Below we illustrate and prove that -1 and 986 multiply to -986 and add up to 985:

-1 × 986 = -986
-1 + 986 = 985

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

x² + 985x - 986 = 0

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

(x - 1 ) (x + 986)

To summarize, since -1 and 986 multiply to -986 and add up 985, you know that the following is true:

x² + 985x - 986 = (x - 1 ) (x + 986)
