Here we answer the question: "What two numbers multiply to 680 and add up to -93?"
The answer to your question is:
-85 and -8
Below we illustrate and prove that -85 and -8 multiply to 680 and add up to -93:
-85 × -8 = 680
-85 + -8 = -93
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 93x + 680 = 0
If so, the solution to factor the quadratic equation above is:
(x - 85 ) (x - 8)
To summarize, since -85 and -8 multiply to 680 and add up -93, you know that the following is true:
x2 - 93x + 680 = (x - 85 ) (x - 8)
