What two numbers multiply to -429 and add up to -20?

Here we answer the question: "What two numbers multiply to -429 and add up to -20?"

The answer to your question is:

-33 and 13

Below we illustrate and prove that -33 and 13 multiply to -429 and add up to -20:

-33 × 13 = -429
-33 + 13 = -20

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

x² - 20x - 429 = 0

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

(x - 33 ) (x + 13)

To summarize, since -33 and 13 multiply to -429 and add up -20, you know that the following is true:

x² - 20x - 429 = (x - 33 ) (x + 13)
