Here we answer the question: "What two numbers multiply to -623 and add up to -82?"
The answer to your question is:
-89 and 7
Below we illustrate and prove that -89 and 7 multiply to -623 and add up to -82:
-89 × 7 = -623
-89 + 7 = -82
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 82x - 623 = 0
If so, the solution to factor the quadratic equation above is:
(x - 89 ) (x + 7)
To summarize, since -89 and 7 multiply to -623 and add up -82, you know that the following is true:
x2 - 82x - 623 = (x - 89 ) (x + 7)
