What two numbers multiply to -799 and add up to 798?

Here we answer the question: "What two numbers multiply to -799 and add up to 798?"

The answer to your question is:

-1 and 799

Below we illustrate and prove that -1 and 799 multiply to -799 and add up to 798:

-1 × 799 = -799
-1 + 799 = 798

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

x² + 798x - 799 = 0

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

(x - 1 ) (x + 799)

To summarize, since -1 and 799 multiply to -799 and add up 798, you know that the following is true:

x² + 798x - 799 = (x - 1 ) (x + 799)
