Here we answer the question: "What two numbers multiply to -820 and add up to 159?"
The answer to your question is:
-5 and 164
Below we illustrate and prove that -5 and 164 multiply to -820 and add up to 159:
-5 × 164 = -820
-5 + 164 = 159
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 159x - 820 = 0
If so, the solution to factor the quadratic equation above is:
(x - 5 ) (x + 164)
To summarize, since -5 and 164 multiply to -820 and add up 159, you know that the following is true:
x2 + 159x - 820 = (x - 5 ) (x + 164)
