What two numbers multiply to -428 and add up to -103?

Here we answer the question: "What two numbers multiply to -428 and add up to -103?"

The answer to your question is:

-107 and 4

Below we illustrate and prove that -107 and 4 multiply to -428 and add up to -103:

-107 × 4 = -428
-107 + 4 = -103

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

x² - 103x - 428 = 0

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

(x - 107 ) (x + 4)

To summarize, since -107 and 4 multiply to -428 and add up -103, you know that the following is true:

x² - 103x - 428 = (x - 107 ) (x + 4)
