What two numbers multiply to 428 and add up to -111?

Here we answer the question: "What two numbers multiply to 428 and add up to -111?"

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 -111:

-107 × -4 = 428
-107 + -4 = -111

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

x² - 111x + 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 -111, you know that the following is true:

x² - 111x + 428 = (x - 107 ) (x - 4)
