What two numbers multiply to -300 and add up to -20?

Here we answer the question: "What two numbers multiply to -300 and add up to -20?"

The answer to your question is:

-30 and 10

Below we illustrate and prove that -30 and 10 multiply to -300 and add up to -20:

-30 × 10 = -300
-30 + 10 = -20

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

x² - 20x - 300 = 0

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

(x - 30 ) (x + 10)

To summarize, since -30 and 10 multiply to -300 and add up -20, you know that the following is true:

x² - 20x - 300 = (x - 30 ) (x + 10)
