What two numbers multiply to -899 and add up to 898?

Here we answer the question: "What two numbers multiply to -899 and add up to 898?"

The answer to your question is:

-1 and 899

Below we illustrate and prove that -1 and 899 multiply to -899 and add up to 898:

-1 × 899 = -899
-1 + 899 = 898

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

x² + 898x - 899 = 0

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

(x - 1 ) (x + 899)

To summarize, since -1 and 899 multiply to -899 and add up 898, you know that the following is true:

x² + 898x - 899 = (x - 1 ) (x + 899)
