What two numbers multiply to -60 and add up to -4?

Here we answer the question: "What two numbers multiply to -60 and add up to -4?"

The answer to your question is:

-10 and 6

Below we illustrate and prove that -10 and 6 multiply to -60 and add up to -4:

-10 × 6 = -60
-10 + 6 = -4

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

x² - 4x - 60 = 0

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

(x - 10 ) (x + 6)

To summarize, since -10 and 6 multiply to -60 and add up -4, you know that the following is true:

x² - 4x - 60 = (x - 10 ) (x + 6)
