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:

-13 and 33

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

-13 × 33 = -429
-13 + 33 = 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 - 13 ) (x + 33)

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

x² + 20x - 429 = (x - 13 ) (x + 33)
