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:

-38 and 15

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

-38 × 15 = -570
-38 + 15 = -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 - 38 ) (x + 15)

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

x² - 23x - 570 = (x - 38 ) (x + 15)
