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:

4 and 107

Below we illustrate and prove that 4 and 107 multiply to 428 and add up to 111:

4 × 107 = 428
4 + 107 = 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 + 4 ) (x + 107)

To summarize, since 4 and 107 multiply to 428 and add up 111, you know that the following is true:

x² + 111x + 428 = (x + 4 ) (x + 107)
