Here we answer the question: "What two numbers multiply to -541 and add up to 540?"
The answer to your question is:
-1 and 541
Below we illustrate and prove that -1 and 541 multiply to -541 and add up to 540:
-1 × 541 = -541
-1 + 541 = 540
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 540x - 541 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 541)
To summarize, since -1 and 541 multiply to -541 and add up 540, you know that the following is true:
x2 + 540x - 541 = (x - 1 ) (x + 541)
