What two numbers multiply to -76 and add up to -15?

Here we answer the question: "What two numbers multiply to -76 and add up to -15?"

The answer to your question is:

-19 and 4

Below we illustrate and prove that -19 and 4 multiply to -76 and add up to -15:

-19 × 4 = -76
-19 + 4 = -15

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

x² - 15x - 76 = 0

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

(x - 19 ) (x + 4)

To summarize, since -19 and 4 multiply to -76 and add up -15, you know that the following is true:

x² - 15x - 76 = (x - 19 ) (x + 4)
