Here we answer the question: "What two numbers multiply to -850 and add up to 165?"
The answer to your question is:
-5 and 170
Below we illustrate and prove that -5 and 170 multiply to -850 and add up to 165:
-5 × 170 = -850
-5 + 170 = 165
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 165x - 850 = 0
If so, the solution to factor the quadratic equation above is:
(x - 5 ) (x + 170)
To summarize, since -5 and 170 multiply to -850 and add up 165, you know that the following is true:
x2 + 165x - 850 = (x - 5 ) (x + 170)
