What two numbers multiply to -520 and add up to -126?

Here we answer the question: "What two numbers multiply to -520 and add up to -126?"

The answer to your question is:

-130 and 4

Below we illustrate and prove that -130 and 4 multiply to -520 and add up to -126:

-130 × 4 = -520
-130 + 4 = -126

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

x² - 126x - 520 = 0

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

(x - 130 ) (x + 4)

To summarize, since -130 and 4 multiply to -520 and add up -126, you know that the following is true:

x² - 126x - 520 = (x - 130 ) (x + 4)
