What two numbers multiply to -300 and add up to -5?

Here we answer the question: "What two numbers multiply to -300 and add up to -5?"

The answer to your question is:

-20 and 15

Below we illustrate and prove that -20 and 15 multiply to -300 and add up to -5:

-20 × 15 = -300
-20 + 15 = -5

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

x² - 5x - 300 = 0

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

(x - 20 ) (x + 15)

To summarize, since -20 and 15 multiply to -300 and add up -5, you know that the following is true:

x² - 5x - 300 = (x - 20 ) (x + 15)
