What two numbers multiply to -960 and add up to 478?

Here we answer the question: "What two numbers multiply to -960 and add up to 478?"

The answer to your question is:

-2 and 480

Below we illustrate and prove that -2 and 480 multiply to -960 and add up to 478:

-2 × 480 = -960
-2 + 480 = 478

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

x² + 478x - 960 = 0

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

(x - 2 ) (x + 480)

To summarize, since -2 and 480 multiply to -960 and add up 478, you know that the following is true:

x² + 478x - 960 = (x - 2 ) (x + 480)
