What two numbers multiply to -960 and add up to 49?

Here we answer the question: "What two numbers multiply to -960 and add up to 49?"

The answer to your question is:

-15 and 64

Below we illustrate and prove that -15 and 64 multiply to -960 and add up to 49:

-15 × 64 = -960
-15 + 64 = 49

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

x² + 49x - 960 = 0

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

(x - 15 ) (x + 64)

To summarize, since -15 and 64 multiply to -960 and add up 49, you know that the following is true:

x² + 49x - 960 = (x - 15 ) (x + 64)
