Here we answer the question: "What two numbers multiply to -310 and add up to 57?"
The answer to your question is:
-5 and 62
Below we illustrate and prove that -5 and 62 multiply to -310 and add up to 57:
-5 × 62 = -310
-5 + 62 = 57
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 57x - 310 = 0
If so, the solution to factor the quadratic equation above is:
(x - 5 ) (x + 62)
To summarize, since -5 and 62 multiply to -310 and add up 57, you know that the following is true:
x2 + 57x - 310 = (x - 5 ) (x + 62)
