What two numbers multiply to 520 and add up to -53?

Here we answer the question: "What two numbers multiply to 520 and add up to -53?"

The answer to your question is:

-40 and -13

Below we illustrate and prove that -40 and -13 multiply to 520 and add up to -53:

-40 × -13 = 520
-40 + -13 = -53

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

x² - 53x + 520 = 0

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

(x - 40 ) (x - 13)

To summarize, since -40 and -13 multiply to 520 and add up -53, you know that the following is true:

x² - 53x + 520 = (x - 40 ) (x - 13)
