What two numbers multiply to -960 and add up to 28?

Here we answer the question: "What two numbers multiply to -960 and add up to 28?"

The answer to your question is:

-20 and 48

Below we illustrate and prove that -20 and 48 multiply to -960 and add up to 28:

-20 × 48 = -960
-20 + 48 = 28

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 28x - 960 = 0

If so, the solution to factor the quadratic equation above is:

(x - 20 ) (x + 48)

To summarize, since -20 and 48 multiply to -960 and add up 28, you know that the following is true:

x² + 28x - 960 = (x - 20 ) (x + 48)
