What two numbers multiply to 520 and add up to -73?

Here we answer the question: "What two numbers multiply to 520 and add up to -73?"

The answer to your question is:

-65 and -8

Below we illustrate and prove that -65 and -8 multiply to 520 and add up to -73:

-65 × -8 = 520
-65 + -8 = -73

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

x² - 73x + 520 = 0

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

(x - 65 ) (x - 8)

To summarize, since -65 and -8 multiply to 520 and add up -73, you know that the following is true:

x² - 73x + 520 = (x - 65 ) (x - 8)
