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

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

The answer to your question is:

-985 and -1

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

-985 × -1 = 985
-985 + -1 = -986

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

x² - 986x + 985 = 0

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

(x - 985 ) (x - 1)

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

x² - 986x + 985 = (x - 985 ) (x - 1)
