What two numbers multiply to -798 and add up to 23?

Here we answer the question: "What two numbers multiply to -798 and add up to 23?"

The answer to your question is:

-19 and 42

Below we illustrate and prove that -19 and 42 multiply to -798 and add up to 23:

-19 × 42 = -798
-19 + 42 = 23

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

x² + 23x - 798 = 0

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

(x - 19 ) (x + 42)

To summarize, since -19 and 42 multiply to -798 and add up 23, you know that the following is true:

x² + 23x - 798 = (x - 19 ) (x + 42)
