What two numbers multiply to -513 and add up to -168?

Here we answer the question: "What two numbers multiply to -513 and add up to -168?"

The answer to your question is:

-171 and 3

Below we illustrate and prove that -171 and 3 multiply to -513 and add up to -168:

-171 × 3 = -513
-171 + 3 = -168

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

x² - 168x - 513 = 0

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

(x - 171 ) (x + 3)

To summarize, since -171 and 3 multiply to -513 and add up -168, you know that the following is true:

x² - 168x - 513 = (x - 171 ) (x + 3)
