Here we answer the question: "What two numbers multiply to -311 and add up to 310?"
The answer to your question is:
-1 and 311
Below we illustrate and prove that -1 and 311 multiply to -311 and add up to 310:
-1 × 311 = -311
-1 + 311 = 310
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 310x - 311 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 311)
To summarize, since -1 and 311 multiply to -311 and add up 310, you know that the following is true:
x2 + 310x - 311 = (x - 1 ) (x + 311)
