What two numbers multiply to 558 and add up to -71?

Here we answer the question: "What two numbers multiply to 558 and add up to -71?"

The answer to your question is:

-62 and -9

Below we illustrate and prove that -62 and -9 multiply to 558 and add up to -71:

-62 × -9 = 558
-62 + -9 = -71

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

x² - 71x + 558 = 0

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

(x - 62 ) (x - 9)

To summarize, since -62 and -9 multiply to 558 and add up -71, you know that the following is true:

x² - 71x + 558 = (x - 62 ) (x - 9)
