Here we answer the question: "What two numbers multiply to 847 and add up to -88?"
The answer to your question is:
-77 and -11
Below we illustrate and prove that -77 and -11 multiply to 847 and add up to -88:
-77 × -11 = 847
-77 + -11 = -88
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 88x + 847 = 0
If so, the solution to factor the quadratic equation above is:
(x - 77 ) (x - 11)
To summarize, since -77 and -11 multiply to 847 and add up -88, you know that the following is true:
x2 - 88x + 847 = (x - 77 ) (x - 11)
