What two numbers multiply to -570 and add up to 23?

Here we answer the question: "What two numbers multiply to -570 and add up to 23?"

The answer to your question is:

-15 and 38

Below we illustrate and prove that -15 and 38 multiply to -570 and add up to 23:

-15 × 38 = -570
-15 + 38 = 23

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

x² + 23x - 570 = 0

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

(x - 15 ) (x + 38)

To summarize, since -15 and 38 multiply to -570 and add up 23, you know that the following is true:

x² + 23x - 570 = (x - 15 ) (x + 38)
