What two numbers multiply to -437 and add up to 4?

Here we answer the question: "What two numbers multiply to -437 and add up to 4?"

The answer to your question is:

-19 and 23

Below we illustrate and prove that -19 and 23 multiply to -437 and add up to 4:

-19 × 23 = -437
-19 + 23 = 4

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

x² + 4x - 437 = 0

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

(x - 19 ) (x + 23)

To summarize, since -19 and 23 multiply to -437 and add up 4, you know that the following is true:

x² + 4x - 437 = (x - 19 ) (x + 23)
