Here we answer the question: "What two numbers multiply to -616 and add up to 69?"
The answer to your question is:
-8 and 77
Below we illustrate and prove that -8 and 77 multiply to -616 and add up to 69:
-8 × 77 = -616
-8 + 77 = 69
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 69x - 616 = 0
If so, the solution to factor the quadratic equation above is:
(x - 8 ) (x + 77)
To summarize, since -8 and 77 multiply to -616 and add up 69, you know that the following is true:
x2 + 69x - 616 = (x - 8 ) (x + 77)
