Here we answer the question: "What two numbers multiply to 930 and add up to -61?"
The answer to your question is:
-31 and -30
Below we illustrate and prove that -31 and -30 multiply to 930 and add up to -61:
-31 × -30 = 930
-31 + -30 = -61
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 61x + 930 = 0
If so, the solution to factor the quadratic equation above is:
(x - 31 ) (x - 30)
To summarize, since -31 and -30 multiply to 930 and add up -61, you know that the following is true:
x2 - 61x + 930 = (x - 31 ) (x - 30)
