What two numbers multiply to -424 and add up to -45?

Here we answer the question: "What two numbers multiply to -424 and add up to -45?"

The answer to your question is:

-53 and 8

Below we illustrate and prove that -53 and 8 multiply to -424 and add up to -45:

-53 × 8 = -424
-53 + 8 = -45

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

x² - 45x - 424 = 0

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

(x - 53 ) (x + 8)

To summarize, since -53 and 8 multiply to -424 and add up -45, you know that the following is true:

x² - 45x - 424 = (x - 53 ) (x + 8)
