What two numbers multiply to -256 and add up to 60?

Here we answer the question: "What two numbers multiply to -256 and add up to 60?"

The answer to your question is:

-4 and 64

Below we illustrate and prove that -4 and 64 multiply to -256 and add up to 60:

-4 × 64 = -256
-4 + 64 = 60

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

x² + 60x - 256 = 0

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

(x - 4 ) (x + 64)

To summarize, since -4 and 64 multiply to -256 and add up 60, you know that the following is true:

x² + 60x - 256 = (x - 4 ) (x + 64)
