What two numbers multiply to -545 and add up to 544?

Here we answer the question: "What two numbers multiply to -545 and add up to 544?"

The answer to your question is:

-1 and 545

Below we illustrate and prove that -1 and 545 multiply to -545 and add up to 544:

-1 × 545 = -545
-1 + 545 = 544

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

x² + 544x - 545 = 0

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

(x - 1 ) (x + 545)

To summarize, since -1 and 545 multiply to -545 and add up 544, you know that the following is true:

x² + 544x - 545 = (x - 1 ) (x + 545)
