Here we answer the question: "What two numbers multiply to -516 and add up to -80?"

The answer to your question is:

-86 and 6


Below we illustrate and prove that -86 and 6 multiply to -516 and add up to -80:

-86 × 6 = -516
-86 + 6 = -80

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

x2 - 80x - 516 = 0

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

(x - 86 ) (x + 6)

To summarize, since -86 and 6 multiply to -516 and add up -80, you know that the following is true:

x2 - 80x - 516 = (x - 86 ) (x + 6)
