What two numbers multiply to -828 and add up to -13?

Here we answer the question: "What two numbers multiply to -828 and add up to -13?"

The answer to your question is:

-36 and 23

Below we illustrate and prove that -36 and 23 multiply to -828 and add up to -13:

-36 × 23 = -828
-36 + 23 = -13

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

x² - 13x - 828 = 0

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

(x - 36 ) (x + 23)

To summarize, since -36 and 23 multiply to -828 and add up -13, you know that the following is true:

x² - 13x - 828 = (x - 36 ) (x + 23)
