Here we answer the question: "What two numbers multiply to 680 and add up to -54?"
The answer to your question is:
-34 and -20
Below we illustrate and prove that -34 and -20 multiply to 680 and add up to -54:
-34 × -20 = 680
-34 + -20 = -54
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 54x + 680 = 0
If so, the solution to factor the quadratic equation above is:
(x - 34 ) (x - 20)
To summarize, since -34 and -20 multiply to 680 and add up -54, you know that the following is true:
x2 - 54x + 680 = (x - 34 ) (x - 20)
