Here we answer the question: "What two numbers multiply to 86 and add up to -87?"

The answer to your question is:

-86 and -1

Below we illustrate and prove that -86 and -1 multiply to 86 and add up to -87:

-86 × -1 = 86
-86 + -1 = -87

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

x² - 87x + 86 = 0

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

(x - 86 ) (x - 1)

To summarize, since -86 and -1 multiply to 86 and add up -87, you know that the following is true:

x² - 87x + 86 = (x - 86 ) (x - 1)
