Here we answer the question: "What two numbers multiply to -385 and add up to -48?"
The answer to your question is:
-55 and 7
Below we illustrate and prove that -55 and 7 multiply to -385 and add up to -48:
-55 × 7 = -385
-55 + 7 = -48
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 48x - 385 = 0
If so, the solution to factor the quadratic equation above is:
(x - 55 ) (x + 7)
To summarize, since -55 and 7 multiply to -385 and add up -48, you know that the following is true:
x2 - 48x - 385 = (x - 55 ) (x + 7)
