What two numbers multiply to -510 and add up to -253?

Here we answer the question: "What two numbers multiply to -510 and add up to -253?"

The answer to your question is:

-255 and 2

Below we illustrate and prove that -255 and 2 multiply to -510 and add up to -253:

-255 × 2 = -510
-255 + 2 = -253

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

x² - 253x - 510 = 0

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

(x - 255 ) (x + 2)

To summarize, since -255 and 2 multiply to -510 and add up -253, you know that the following is true:

x² - 253x - 510 = (x - 255 ) (x + 2)
