Here we answer the question: "What two numbers multiply to -460 and add up to 459?"
The answer to your question is:
-1 and 460
Below we illustrate and prove that -1 and 460 multiply to -460 and add up to 459:
-1 × 460 = -460
-1 + 460 = 459
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 459x - 460 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 460)
To summarize, since -1 and 460 multiply to -460 and add up 459, you know that the following is true:
x2 + 459x - 460 = (x - 1 ) (x + 460)
