What two numbers multiply to -60 and add up to -11?

Here we answer the question: "What two numbers multiply to -60 and add up to -11?"

The answer to your question is:

-15 and 4

Below we illustrate and prove that -15 and 4 multiply to -60 and add up to -11:

-15 × 4 = -60
-15 + 4 = -11

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

x² - 11x - 60 = 0

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

(x - 15 ) (x + 4)

To summarize, since -15 and 4 multiply to -60 and add up -11, you know that the following is true:

x² - 11x - 60 = (x - 15 ) (x + 4)
