What two numbers multiply to 345 and add up to -38?

Here we answer the question: "What two numbers multiply to 345 and add up to -38?"

The answer to your question is:

-23 and -15

Below we illustrate and prove that -23 and -15 multiply to 345 and add up to -38:

-23 × -15 = 345
-23 + -15 = -38

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

x² - 38x + 345 = 0

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

(x - 23 ) (x - 15)

To summarize, since -23 and -15 multiply to 345 and add up -38, you know that the following is true:

x² - 38x + 345 = (x - 23 ) (x - 15)
