What two numbers multiply to -89 and add up to 88?

Here we answer the question: "What two numbers multiply to -89 and add up to 88?"

The answer to your question is:

-1 and 89

Below we illustrate and prove that -1 and 89 multiply to -89 and add up to 88:

-1 × 89 = -89
-1 + 89 = 88

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

x² + 88x - 89 = 0

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

(x - 1 ) (x + 89)

To summarize, since -1 and 89 multiply to -89 and add up 88, you know that the following is true:

x² + 88x - 89 = (x - 1 ) (x + 89)
