Here we answer the question: "What two numbers multiply to -540 and add up to -84?"
The answer to your question is:
-90 and 6
Below we illustrate and prove that -90 and 6 multiply to -540 and add up to -84:
-90 × 6 = -540
-90 + 6 = -84
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 84x - 540 = 0
If so, the solution to factor the quadratic equation above is:
(x - 90 ) (x + 6)
To summarize, since -90 and 6 multiply to -540 and add up -84, you know that the following is true:
x2 - 84x - 540 = (x - 90 ) (x + 6)
