What two numbers multiply to -549 and add up to 548?

Here we answer the question: "What two numbers multiply to -549 and add up to 548?"

The answer to your question is:

-1 and 549

Below we illustrate and prove that -1 and 549 multiply to -549 and add up to 548:

-1 × 549 = -549
-1 + 549 = 548

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

x² + 548x - 549 = 0

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

(x - 1 ) (x + 549)

To summarize, since -1 and 549 multiply to -549 and add up 548, you know that the following is true:

x² + 548x - 549 = (x - 1 ) (x + 549)
