What two numbers multiply to -440 and add up to 83?

Here we answer the question: "What two numbers multiply to -440 and add up to 83?"

The answer to your question is:

-5 and 88

Below we illustrate and prove that -5 and 88 multiply to -440 and add up to 83:

-5 × 88 = -440
-5 + 88 = 83

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

x² + 83x - 440 = 0

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

(x - 5 ) (x + 88)

To summarize, since -5 and 88 multiply to -440 and add up 83, you know that the following is true:

x² + 83x - 440 = (x - 5 ) (x + 88)
