What two numbers multiply to 87 and add up to -88?

Here we answer the question: "What two numbers multiply to 87 and add up to -88?"

The answer to your question is:

-87 and -1

Below we illustrate and prove that -87 and -1 multiply to 87 and add up to -88:

-87 × -1 = 87
-87 + -1 = -88

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

x² - 88x + 87 = 0

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

(x - 87 ) (x - 1)

To summarize, since -87 and -1 multiply to 87 and add up -88, you know that the following is true:

x² - 88x + 87 = (x - 87 ) (x - 1)
