Here we answer the question: "What two numbers multiply to -930 and add up to -83?"
The answer to your question is:
-93 and 10
Below we illustrate and prove that -93 and 10 multiply to -930 and add up to -83:
-93 × 10 = -930
-93 + 10 = -83
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 83x - 930 = 0
If so, the solution to factor the quadratic equation above is:
(x - 93 ) (x + 10)
To summarize, since -93 and 10 multiply to -930 and add up -83, you know that the following is true:
x2 - 83x - 930 = (x - 93 ) (x + 10)
