What two numbers multiply to -57 and add up to -16?

Here we answer the question: "What two numbers multiply to -57 and add up to -16?"

The answer to your question is:

-19 and 3

Below we illustrate and prove that -19 and 3 multiply to -57 and add up to -16:

-19 × 3 = -57
-19 + 3 = -16

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

x² - 16x - 57 = 0

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

(x - 19 ) (x + 3)

To summarize, since -19 and 3 multiply to -57 and add up -16, you know that the following is true:

x² - 16x - 57 = (x - 19 ) (x + 3)
