What two numbers multiply to -380 and add up to -28?

Here we answer the question: "What two numbers multiply to -380 and add up to -28?"

The answer to your question is:

-38 and 10

Below we illustrate and prove that -38 and 10 multiply to -380 and add up to -28:

-38 × 10 = -380
-38 + 10 = -28

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

x² - 28x - 380 = 0

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

(x - 38 ) (x + 10)

To summarize, since -38 and 10 multiply to -380 and add up -28, you know that the following is true:

x² - 28x - 380 = (x - 38 ) (x + 10)
