Here we answer the question: "What two numbers multiply to -395 and add up to -74?"
The answer to your question is:
-79 and 5
Below we illustrate and prove that -79 and 5 multiply to -395 and add up to -74:
-79 × 5 = -395
-79 + 5 = -74
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 74x - 395 = 0
If so, the solution to factor the quadratic equation above is:
(x - 79 ) (x + 5)
To summarize, since -79 and 5 multiply to -395 and add up -74, you know that the following is true:
x2 - 74x - 395 = (x - 79 ) (x + 5)
