What two numbers multiply to 558 and add up to 49?

Here we answer the question: "What two numbers multiply to 558 and add up to 49?"

The answer to your question is:

18 and 31

Below we illustrate and prove that 18 and 31 multiply to 558 and add up to 49:

18 × 31 = 558
18 + 31 = 49

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

x² + 49x + 558 = 0

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

(x + 18 ) (x + 31)

To summarize, since 18 and 31 multiply to 558 and add up 49, you know that the following is true:

x² + 49x + 558 = (x + 18 ) (x + 31)
