Here we answer the question: "What two numbers multiply to 384 and add up to -40?"
The answer to your question is:
-24 and -16
Below we illustrate and prove that -24 and -16 multiply to 384 and add up to -40:
-24 × -16 = 384
-24 + -16 = -40
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 40x + 384 = 0
If so, the solution to factor the quadratic equation above is:
(x - 24 ) (x - 16)
To summarize, since -24 and -16 multiply to 384 and add up -40, you know that the following is true:
x2 - 40x + 384 = (x - 24 ) (x - 16)
