What two numbers multiply to -550 and add up to 549?

Here we answer the question: "What two numbers multiply to -550 and add up to 549?"

The answer to your question is:

-1 and 550

Below we illustrate and prove that -1 and 550 multiply to -550 and add up to 549:

-1 × 550 = -550
-1 + 550 = 549

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

x² + 549x - 550 = 0

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

(x - 1 ) (x + 550)

To summarize, since -1 and 550 multiply to -550 and add up 549, you know that the following is true:

x² + 549x - 550 = (x - 1 ) (x + 550)
