What two numbers multiply to 510 and add up to -91?

Here we answer the question: "What two numbers multiply to 510 and add up to -91?"

The answer to your question is:

-85 and -6

Below we illustrate and prove that -85 and -6 multiply to 510 and add up to -91:

-85 × -6 = 510
-85 + -6 = -91

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

x² - 91x + 510 = 0

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

(x - 85 ) (x - 6)

To summarize, since -85 and -6 multiply to 510 and add up -91, you know that the following is true:

x² - 91x + 510 = (x - 85 ) (x - 6)
