Here we answer the question: "What two numbers multiply to -960 and add up to -16?"
The answer to your question is:
-40 and 24
Below we illustrate and prove that -40 and 24 multiply to -960 and add up to -16:
-40 × 24 = -960
-40 + 24 = -16
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 16x - 960 = 0
If so, the solution to factor the quadratic equation above is:
(x - 40 ) (x + 24)
To summarize, since -40 and 24 multiply to -960 and add up -16, you know that the following is true:
x2 - 16x - 960 = (x - 40 ) (x + 24)
